RM 3.4.45 doesn't install on Windows10 : a first error (code 2503) is followed by a second error (code 2502)

Hello !

I've just got a new laptop, a refurbished one that have been reset, and Windows 10 (family version) reinstalled. I wanted to dedicate it to Rig manager...

I did all the many windows updates needed until there was no more update found, so that Windows10 is brand new and up to date now.

But when running the installer of the last RM (v3.4.45) it runs approximately half the progression bar, and then stops, shows a couple of messages including these two error codes ( 2502 and 2503), and says it closes without being able to install RM.

I found only one thread mentioning this error code, the person fixed it by setting "total control" in the security properties of the Windows temp folder, but it had no effect in my case.

Please help

(PS : the laptop model is HP elitebook 840 G3)

Is this that cheap version of Windows (Windows S) that only lets you run programs from the Microsoft Store?

No, it doesn't seem to be that....

And ok Burkhard, I'll open a ticket!

thanks !

Yes it worked !!!!

Your 1st link gave the solution Yoda. In fact I thought I tried their solution already but the force wasn't with me, I had to try harder. Thanks for having pushed me to try again
