For the longest time, I wasn't able to install Rejuvenate on my Vita. I kept getting error 800100020 on my Vita. If anyone else is having this problem, don't worry as I've figured out a solution. This is what you need to do:
1) Run CMD as administrator
2) Copy and paste:
Code: Select all
setx MSBUILDENABLEALLPROPERTYFUNCTIONS 1
4) PROFIT
Hope it helped
