Hi I really tried a lot to make it work but it always tells me that WinOLS 5 already exists and blocks my functions of exporting or changing bin files in winols. I'm working in HyperV with Windows 11 i cleaned registry appdata programmdata like you said in your comments here but still everytime it tells me that WinOLS 5 already exists and my funkcions are restricted. I also tried it with Network connection completely off everytime the same error [MSG2581] could you help me out pls?

thank youPost #50
Thanks for suggestion.
For me the program only works with internet disconnected now (on W10 LTSC IoT).
I will try to remove all leftovers and reinstall cleanly, Revo uninstaller helps with that.
Even though I blocked inbound/outbound to all executives in EVC folder, I forgot to set real time scan exclusions for that folder and files.
After few days and restarts windows defender messed up ols.exe
Now with the internet connected it says "Your system date is wrong. Please correct it and restart WinOLS."

Yeah, that lines up with what you found. If Defender quarantined or partially cleaned ols.exe, the patch gets reverted and you're back to the date/license check kicking in with internet on. That's why it only runs offline now.
Clean approach:
- Do the full removal with Revo, then delete leftover
C:\ProgramData\EVCand any EVC folder under your user profile as you planned. - Before reinstalling, add the install folder to Defender exclusions (both folder and process):
C:\Program Files (x86)\EVC. Set it under Virus & threat protection → Manage settings → Exclusions. - Reinstall, run the patch step, then re-add your outbound firewall blocks for
ols.exeandolslaunch.exe.
The key point is the exclusion has to be in place before the patch runs, otherwise Defender can grab the patched exe on the next scan and you're back to square one.
If it still throws the date error after a clean reinstall with exclusions set, tell me your exact WinOLS build and whether the patch step reported success, and I'll help narrow it down.
