I’m running Windows 11 Home and having trouble installing the newest version (1.2.3). Windows defender blocks the installation, but if I bypass that it gives the following error: Unable to execute the file in the temporary directory. Setup aborted. Error 5: Access is denied.
I tried running it as administrator too, but got the same error.
I’ve tried to install it from my Downloads folder and Desktop with no success. I have installed innumerable other executables from both of these locations. I have all necessary permissions on the temp folder. Previous installation files (Siril 1.2.1 and 1.2.2) work fine in either location.
Disabling antivirus did the trick…
I am running Kaspersky and it definitely does not like this installer. It stopped the process and deleted all material from the temp directory as soon as I reactivated the antivirus.
