Problem "When I start any application of the MS Office 2010.. I have to wait 2mins for the 'Configuring Microsoft Office Enterprise 2010..." or "configuration progress" dialog..." pop-up...


Solution:
Step 1:
Open Run (Press Windows key + R) copy and paste the following commands one at a time and then press ENTER. You may receive a prompt to click on the continue/allow button.

Ensure to back-up the registry using the steps givenhere before modification.
reg add HKCU\Software\Microsoft\Office\14.0\Word\Options /v NoReReg /t REG_DWORD /d 1
reg add HKCU\Software\Microsoft\Office\14.0\Excel\Options /v NoReReg /t REG_DWORD /d 1
reg add HKCU\Software\Microsoft\Office\14.0\Access\Options /v NoReReg /t REG_DWORD /d 1
reg add HKCU\Software\Microsoft\Office\14.0\Powerpoint\Options /v NoReReg /t REG_DWORD /d 1


Step 2 :
That is it. Office 2010 might want to have one more spin round the block with it's configuration dialog box, but that should be it.
C: \Program Files>Common Files>microsoft shared>OFFICE14>Office Setup Controller>SETUP.exe change to SETUPold.exe

Finally..try to open the target Office applications and verify if it fixes the issue.
Cheer!!
