Visual Studio Installation Error - Check that you have permissions & enough space in Visual Studio directory.

I was installing Visual Studio 2005 on a Windows 7 Enterprise machine and I got the following error during the installation process -

Visual Studio 2005 Installation Error


Reason -

Visual Studio 2005 setup was run from a ISO image mounted to a virtual drive on Windows 7. Apparently, Visual Studio installation has some permission issues when started from a virtual drive.


Resolution -

Easiest option is to burn the ISO image to a DVD & install from a DVD disc.

Windows Activation - "Activation Failed. The product key is already being used on another pc."

I had previously installed & later uninstalled Windows 8 Pro on Parallels Desktop 8 on my MBP. Yesterday, I decided to re-install Windows 8 Pro on Parallel 8. After the installation and during the Windows activation process, I got an error something like -
Activation Failed. The product key is already being used on another pc.

 After some googling I found that it is kind of a known issue and I followed some of the recommend steps to reactivate by resetting the windows key. Unfortunately, that did not work. After some trial & errors, I finally decided to do windows activation over the phone through Microsoft's automated process. Here are the steps I did to activate my Windows license through phone -
  • Opened RegEdit.exe on the Windows machine.
  • Browsed to HKEY_LOCAL_MACHINE/ Software/ Microsoft/ Windows/ CurrentVersion/ Setup/OOBE/
  • Changed MediaBootInstall from 1 to 0.
  • Opened a Command Prompt as an administrator (Right click & Run as Admin).
  • Typed & Executed - slmgr /rearm to reset activation key.
  • A message informed that activation key has been reset.
  • Restarted Windows.
  • After the reboot, again opened a command prompt as an administrator.
  • Typed & Executed - slui.exe 4
  • Now Windows Activation screen asked to select the user country and provided phone numbers & long verification numbers to activate by phone.
  • Called the phone number on the screen and followed the instructions.

NOTE - Even though it is a phone activation, it is fully automated and I did not speak to any human.
