I’ve been using Dotfuscator for years. Nothing has changed, but now when I try to run it, I get:

Could not find a version of the Shelf Life Check library that is runtime compatible with all input assemblies. Highest detected runtime version is v4.0.30319.

(my exe is DotNet 4.7.2 – not sure if they are referring to my runtime or their own?)

I’ve gone back to an old version of everything, which ran through Dotfuscator fine previously, and get the same result. I’m not using the Shelf Life check, but am using the Debugging Check and Tamper Check. If I delete BOTH of these (or disable checks) then it works.

I’m running 6.5.3+7f0b0a9d18. From their website I downloaded the latest (DotfuscatorCE_6.3.0+8b29d6f4a2.vsix) but it fails to install – the error log shows Invalid Certificate (humerously I think it fails the Shelf Life check LOL):

Is Dotfuscator CE not a thing any more? I’ve tried reporting to them but they don’t have a way to do so for Community Edition.

Does anyone have any ideas? Or are there more modern alternatives to Dotfuscator? (free or cheap…. this is just a sideline for me).

I’ve tried old version of my code known to work, updating Dotfuscator but failed, reaching out to PreEmptive and I tried googling it with no helpful results. I tried updating VS2022 to the latest and I tried rebooting. I’m not sure what else I can try.

Thanks in advance.
