Good morning,

I'm going in circles trying to run a PowerShell script. I can run it via cmd or the PowerShell console, but I can't run the script via Wapt.
The return is a very large string of characters when there shouldn't be much of it.
I saw a post that talks about blobs but I don't see how to use it.

Can you help me?

Here are some excerpts

Hi Joël,

When PowerShell commands are run, they are base64 encoded to avoid special character issues (there are many cases where this causes problems). The issue is that this shouldn't be done when loading a file. In your case, the file is rather long, and when it's converted to base64 and passed to the command line, it exceeds the maximum command line length in Windows.

That said, there are many lines in the file that could be easily and efficiently replaced by setuphelper calls. So, in the meantime, you can split it in two or replace part of it with Python code.

I'm opening an internal ticket for this problem.

Best regards,

Denis

Thanks Denis for the feedback

. I'm interested in a RustDesk package generated by Trankil It.

It's a very, very good replacement for TeamViewer and AnyDesk. It can be used on public servers as well as with a home RustDesk server.
I found the result to be far superior to TeamViewer in terms of simplicity, smaller file size, and lower performance.

I've weighed all my arguments and I haven't exaggerated anything.

When will a custom package be available?
