pyinstaller error: "The file cannot be accessed by the system"

[wiseman]

Thanks for this! I was hoping something like this existed, and I googled and was taken directly here; perfect. The release exe works fine for me, but I wanted to add automatic conversion to JPG (Google Maps doesn't seem to be able to handle geotagged PNGs). Unfortunately, when I try to build the exe, I get an error. It's not clear to me what file it's having an issue with.

Hi,

Unfortunately I was unable to replicate your issue.
I was going to suggest to try using a virtual environment which I should have been using anyways. However, that results in Microsoft Defender Antivirus marking the built .exe files as false-positives (related to pyinstaller).

To avoid more problems like these in the future and since this is all on Windows I think the best solution would be to rewrite this app in something more Microsoft-y like C#.
