i am having trouble uninstalling xdk. first it didnt want to log me into the xdk program (windows 8.1) although it worked on the website. than it wanted to update itself and tried to but didnt succeed. than i had two entries of xdk (version 0.195 and 0.1878) in the windows software list. so i tried to uninstall both but both uninstallers give an unexpected error and shut down. meanwhile xdk doesnt start because it cant find the directory under program files(x86)/xdk/xdk. so itried to delete the hkey entries and the files and everything else i know, including the local data. but still, nothing works. installing a freshly downloaded new bundle also doesnt work: again unexpected error. so, what to do?
