New ContributorModel Sim "Invalid time string specified" Error
I found another post from a third party that they have similar issue and resolved it by deleting the register key.
Could you try their method and see if it helps.
***Please make a backup by Export to .reg file, before deleting. As making incorrect changes to the Registry may cause issues to Windows and may cause programs crashing or no longer start***
This is their solution. (not tested and might be risky)
Press "Windows+R" to open the run window, enter 'regedit', find the path HKEY_CURRENT_USERS\Software\ModelTechnology Incorpporated\Modelsim, and delete all the folders.
I suspect something is wrong with your machine, do you see the same issue using a difference machine/PC?
At the same time, try below troubleshooting steps:
- If you are running antivirus software, try to temporarily disable the antivirus software during the Questa software download and installation process.
-Install the software with Administrator privileges.
- Try to download and auto install using the new Quartus installer.
- Check your OS history update, e.g. to check if the issue happen after some specific Window update.

youlexaHi Richard, thank you for providing this solution!
I did some extra steps top make sure everything was cleared out.
1) uninstall quartus and questa
2) remove registers using the provided method
3) restart pc
4) reinstall apps (Quartus 17 and modelsim 10.5b), I reinstalled the versions provided by my school and not the newest versions
After doing these steps I was able to run model sim again without the time string error.
The issue definitely had to do with my machine and not the code, as I mentioned in my original post I had no issues running the same files on my laptop.
Could you also provide the link of where you found this method?
