It's been broken by Windows 10 Update

[ghost]

Bug Description
Trying to start the program results in the program not starting. It creates a ErrorLog.log.

Using this program on a daily bases, I noticed this problem began after Windows 10 installed updates on 11/06/2020 or/and 12/06/2020.

ps. I love the program. It's well constructed, user-friendly, idiot-proof and most importantly it's accurate! Thanks for coding this!

To Reproduce
LMB double click PostScriptumMortarCalculator.exe or RMB and "Open"

Can't seem to reproduce this one with the Win10 updates I currently have on my dev machine, I know that Microsoft are currently doing some weird staggering with their May 2020 update because there were some issues with it so it wouldn't surprise me if it broke this somehow.

The second I get access to the update I'll endeavour to reproduce this and fix it ASAP, cheers for the report.

I've grabbed the most recent available Win10 update and I'm still unable to reproduce this one, this is going to be a difficult one to nail down.

Okay.. well, I downloaded a copy, after having deleted the copy I had. Still get the same problem.

As far a I can tell, the program was working great, but after the a couple of system updates, it stopped. This doesn't mean that that's the reason and since you've tested it, it seems it wasn't. For now, I am completely clueless about what the reason could be, since I didn't change anything to my system.

I will try to find the culprit on my system and will report back whenever I found what's causing this.

Thanks for your time.

I've been religiously checking for and installing updates and seeing if I can get the app to crash, no luck yet.

The only possible thing I could suggest would be to head over to %appdata%/PostScriptumMortarCalculator and just delete the entire folder and see there might've been some issue there.

It's a very long shot but I don't have a lot to go on for this one.

I had the same propblem and deleting the folder %appdata%/PostScriptumMortarCalculator solved it. Thank you
