I recently tried to install MSE x64 on Windows 7 x64 & every time I click on Validate (just before the install is supposed to start), then MSE closes & Windows tells me MSE has stopped responding & I should close it. I have determined that the cause of the problem is my folder permissions. Most of my folders, like Users, AppData, ProgramData have a little golden slot over them. These little slots have appeared just after I shared my Hard Drive to my other PC & the same thing happend there, after I created a HomeGroup & shared folders, they become "Protected" & most programs can't access them. This means that I cannot install certain programs... Such as MSE. So, how the heck do I reverse this folder access protection? This is the cause of my problem & it happens everytime I share folders / drives over my home network. Or is there any other way I can own all of these folders (it'll be a big job to take ownership of each of them)?
