When i was trying to install Electra jailbreak to my ip7+,one error came up so i used Xcode,but when i click on that i get this error-{progress.hpp:87
_assert(false)}. 

Now i have already searched this problem many times and i was not able to find a previous version of impactor. So if you are able to help me out in anyway or send me link of the previous version of the impactor then Thank you so much

I'm having the same issue but here's a link for version 0.9.42 https://yalujailbreak.net/fix-progress-hpp87-error/.

The comment section on this post (https://yalujailbreak.net/cpp-42-cydia-impactor/) shows a lot of people seem to be having the same issues with revoking certificates/deleting App ID.
