Hi @Griz2, what you can do is to add a DM before the Export to Excel containing the following history: If the DM will be empty Rulex will return an error (Action 5) and the Export to Excel won't compute otherwise it will export your data without any changes.

Hi! We were able to replicate and fix the issue, please install the latest Rulex4 version available in the Download section: (Rulex Download - Rulex Community)

What Rulex4 version and build are you running on the VM? Is it the same version you have on your machine? To check this, you have to: 1. Open Rulex 2. Click on Help (top left) -> About

Ok, if it's ok for you I will move this topic to the Rulex4 Forum. Anyway, can you please share with us a dummy prcx that replicates your problem so that we can investigate further? Also your service settings may help to understand the issue. Thank you in advance!

Hi! Are you experiencing these problems with Rulex 4 or Rulex Platfrom?

Hi Griz, yes, there are multiple way to perform the changes of the attributes name using a formula, the one that I suggest you is the following. Let's take as example a data set containing 3 attributes: CLIMBER, name of the climber Best Sport, the highest sport grade reached by the athlete Best Boulder, the highest boulder grade reached by the athlete You decide that "Best" is not representative enough and you want to change the names of all the attributes containing "Best" by replacing "Best" with "Highest". To do that you need to: Insert $names on the left side of the formula Insert the formula that you want to use on the right side, in this case: ifelse(find ($names, "Best") == 1, replace ($names, "Best", "Highest"), $names) I hope it will be useful to you

Hi Griz, You can buy monthly Factory Lite, and then you can deactivate the automatic Renewal as explain in this topic: This won't cause the deletion of your Licence on our Databases, once you will pay again you will be able to use again the same product key and see again your previous flows.

Hi Griz, can you explain more precisely your needs? Maybe with an example of your starting datasets and the one that you want to have at the end? Anyway, Rulex4 and Rulex Platform do not support the style format of Excel

Hi Kuba, looking at the screen I noticed that you are using a Parallels ARM virtual machine, this works for Rulex Platform but not for Rulex 4

Hi @Griz2, if the variable is an integer, you can insert the @Var_name in the filter as in the image below If the variable is nominal or if you want to filter with a string in particular the step to follow are the following: Create a new variable Var_1 Assign to it the function Var_1=ifelse(find($"NameOfTheVariableWhereYouWantToAplyTheFilter",@Var_name),1,0) Filter Var_1 (equal to 1 in case you want to keep all the record with your variable value) Delete Var_1 Let me know if any passage is not clear to you.

Hi Kuba, unfortunately, Rulex 4 is not supported for x32 architectures.

Hi, have you already tried to follow this procedure step by step?

Hi Mike! Does your flow include a Runtime Variables task? In this case be sure to compute it together with the Execute Rulex Flow File task. Otherwise, the Execute Flow would consider the default values for the code variables instead of the values set by the Runtime Variables.

This is a different issue and it seems not be related to the VM. If it is possible for you to share some more content this will be grant us to help you better. Information that may be useful to understand the problem includes: Version and build of Rulex installer that you are using Rulex logs, error log and redir, you can find them there C:\Users\<username>\Rulex\4\Log All the steps that brought you to the error Remember that all the information that you will share on a public forum will be public

Hi Florencia, please open a ticket on Support - Rulex Community

The correct sequence is 1. Microsoft Visual C++ Redistributable 2. Rulex 4 did you follow it?

Hi, have you already downloaded and installed on the VM the latest Microsoft Visual C++ Redistributable supported (X64 Architecture), you will find it to the link Latest supported Visual C++ Redistributable downloads | Microsoft Learn

Hi Julia, have you already tried to follow the steps described here: Furthermore, if you will be still in trouble, can you give us some more information related to your computer (settings) and the steps that brings you to the error.

Hi Jing, we noticed that you were able to pay and join the Rulex academy, if this is not the case, please reach us on the support dedicate section Support - Rulex Community. Additionally, I will move this topic to the general forum. Bye

Hi Andrew! To do this, you can use a tool called "Option Manager" found on Rulex Platform. All you need to do is go to the flow where the tasks whose settings you want to change are located and once it is open click on the "Summary" section on the left (if not already selected) and click on the pencil that is in the top right of this section. Once the Option Manager window is open you can select in the "Summary" section a category of tasks whose settings you want to change or individual tasks whose settings you want to change. After that from the interface you will be able to change all the parametric settings you need. This procedure is also feasible at the level of several flows simultaneously. In fact, by clicking on the name of the environment from the explorer it is possible to select the option "Option Manager," thanks to which it is possible to do the previously described operations. I hope this will come in handy!

Hello again Xiaolu, we managed to find a solution: First thing first you must download the latest version of Parallels In case it is you first VM you can jump to the step 3, otherwise proceed by selecting Get Windows 11 from Microsoft After that you will have to Download Windows 11 It is important that you check that your network options are set as follows (Shared Network) Next step will be to download and install on the VM the latest Microsoft Visual C++ Redistributable supported (X64 Architecture), you will find it to the link Latest supported Visual C++ Redistributable downloads | Microsoft Learn Last of all, proceed with the normal installation of Rulex Platform. When you will run the Platform you will need to allow Rulex Platform, rulexbackend and mosquitto to communicate on the Private networks It is also important that you follow those steps in this exact order. We tested this solution and it was working, let us know if this is the case for you too

Hi Xiaolu! Thanks for reaching out, we are currently working on trying a suitable solution for you, as soon as we have a workaround, we will update you.

Hello Andrew, negative values can appear only for ordered input in Relative Relevance. They mean that that variable is “inversely correlated“ with a particular output value. In other words, rules with that output often contain “<=” inequalities for that input. Of course vice versa for positive relevances. Have a nice day!

Hi Mike! I see two feasible ways without inputting 1050 times: Applying ifelse formulas to all of them (you can use the copy-paste of formulas: you just write one formula, you select “Copy Formula”, then select all the columns and do “Paste Formula”) Pros: fewer tasks Cons: it depends on attribute names You convert all the columns into a long format, you do the operation on the unique remaining column and then convert back to wide format. Pros: it does not depend on attribute names Cons: more tasks and, potentially, more risk of running out of RAM (if the dataset is big, of course). If you want, let me know which path you will choose Have a nice day!

Hi Llewelyn, all the documentation you may need can be found here: Technical Documentation - Rulex Community It is possible to create a workign DB in a shared location in Platform but pay attention to the performance, here you can find the manual page about permissions in Rulex Factory: Permissions in the Factory (rulex.ai) For each page that you cannot find on the documentation you can open a topic directly here: Training & Docs - Rulex Community Best regards
