I have the actual data files preserved but cant see a way to attach a zip file?

Sorry for the late response. If you're still having this problem and would like to get it fixed, please contact me at confuser.net@gmail.com

I'm getting this same error running release v0.4.0.

yck1509 commented 9 years ago

I've rewritten most of the V-Table building process in v0.4.0, so it should not be the same error. Please post your output log for me to have a look.

CoderDennis commented 9 years ago

Below is everything after the assembly loading. It would be helpful if it listed which key it was trying to find in the dictionary. I got the latest code yesterday and after removing the RickRoller class because it was causing an error, the obfuscation succeeds, but it breaks my .exe.

I've add a debug check in VTable construction, please run it and post the resulting log.

Your error is unrelated to this issue. It is most likely caused by some invalid input modules. Is the input modules obfuscated?

badescud commented 9 years ago

Getting similar error. Following the remark that obfuscated input modules could lead to this error ... I figured out that the input assembly was signed prior to run obfuscation. I run the obfuscation on the clean version of the same assembly and the obfuscation succeeded.

Ruffio commented 8 years ago

@badescud do you have a sample that the dev. can have a look at or is it not relevant anymore?
