Windows 7 64 bit on a Dell Inspiron.
Not a major problem -- more of a minor irritation and an "I wonder if anyone else has struck this...?"
Whenever installing a program lately (can't remember how long -- I've been ignoring it for a while), Windows doesn't respond when I click the .exe installer file.
But as soon as I hit Ctrl - Alt - Del and open the Task Manager, Windows suddenly wakes up and installs the program without a hitch. I don't have to do anything in Task Manager; simply opening it is enough. Also, the computer hasn't crashed in this state. If I want to open another already-installed program and use it, I can without any problems. It's just that it completely ignores my command to run the .exe file until I threaten it with Task Manager.
The first couple of times, before I thought of opening Task Manager, I'd double click the .exe file several thousand times, as you do, wondering why it wasn't doing anything. Then, when I opened the Task Manager, it'd try to install the program several thousand times.
Now I know to simply double click the .exe file, then hit Ctrl - Alt - Del, and voila, the program is installed.
What I want to know is, why doesn't Windows install the program in the first place?
FYI, the programs I was having trouble with were (from memory) Dropbox, Skype, memoQ (translation memory software) and a few others I can't remember. I doubt that the programs were the problem though. I'm pretty sure this is a Windows problem.
