Dooser

Hello, issue is now resolved by adding admin rights as you said, I needed to be full administrator for this to work normally, I did not know what you meant by it but now I did watch a few videos and I understand it now, my apologies for this incovnienece and thank you very much for your very kind helpfulness. I wish you a pleasant day. Thank you very much

Yes, the box appears and I say yes, after that the welcome box of the setup wizard appears, I click next and then i get the error, if I press OK i can proceed with the installation but the software does not install then so it is completely useless. I use MSFS2020 from steam.

@John Dowson Hello again, tried everything, but not working. The error occurs on the start of the setup wizard - Launch it, click next, then the error occurs, it does ask me to make changes on my device but I am not sure how to get the admin privileges on my pc, I am pretty sure I have some but don't know how to confirm it. I would prefer then sharing the manual installation file, and if that would not work we could troubleshoot more if that's fine with you. Thanks

Does not work for me, tried extracting it in downloads - not working, tried in various different folders - still the same error - invalid opcode installer corrupted. I have disabled windows defender and added an exlusion to it. It is not working, updated Redistributable - not working. Would really appreciate help Thanks

Okay, I found a new solution i will try it and let you know.

I also tried that, I installed the newest version you have and yet the same.

So, for the past few weeks i´ve been trying to install the FSUIPC, but everytime it shows that the installer corrupted (via the picture) I´ve tried almsot everything. I also tried opening it in a folder that is within a secured windows folder like Program Files or Program Files (x86) Snimek_obrazovky_2024-12-10_212602.png.url
