Fixed: Script debugging with Visual Studio 2010 Premium + IE 11 on Win 7 Ent x64

Spent many hours on this. Here’s what worked for me.

  1. Close VS and IE.
  2. Run cmd like a boss (as Administrator)
  3. Type in

    regsvr32 “C:\Program Files (x86)\Common Files\microsoft shared\VS7Debug\pdm.dll”
    regsvr32 “C:\Program Files (x86)\Common Files\microsoft shared\VS7Debug\msdbg2.dll”

  4. Open regedit and navigate to HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\Main
  5. Create a DWORD(32) value named TabProcGrowth. Leave the value as 0.
  6. Launch VS, script debugging should now work.
