I'm calling exiftool in a personnal software and, after executing it many times in a script, the software cannot be executed anymore.
To solve the problem i had to clear manually the %TEMP% folder. Using the already decompressed app (https://oliverbetz.de/pages/Artikel/ExifTool-for-Windows (https://oliverbetz.de/pages/Artikel/ExifTool-for-Windows)) solves the problem permanently.
OS : Windows 10
Exiftool : 11.94 (exe)
The most common cause would be an anti-virus program, which seems to be borne out by the fact that Oliver's version works, since it operates differently.
Thanks for the reply.
In that case, the anti-virus is clearly not in cause. It's most likely the packaging in exe by PAR which seems to be involved.
For some reason, it became unable to erase existing files in the windows temp directory.
Once the directory pointed by %TEMP% manually deleted, everything came back to normal. However, for my usage, the oliver's version suits better.
