Problem while installing office 2007 / office 2010

Hi,

I just faced one problem while installing MS Office 2010 in my laptop. There is office 2001 already installed in m laptop and that was corrupted and I am to install or upgrade office.
I got the following error during set up:

Microsoft Office suite_name encountered an error during setup.

 

First you have to unistall previous version of office by Microsoft Fix it:

 

For uninstalling Office 2003: Fix it 2003

For uninstalling Office 2007: Fix it 2007

For uninstalling Office 2010: Fix it 2010

Now if you try to install again error will be occured. So one more step to go.

In Windows XP

1. Click Start, click Run, type cmd, and then click OK.
2. Type cd "%allusersprofile%\Application Data\Microsoft Help", and then press ENTER.
3. Type attrib -h rgstrtn.lck, and then press ENTER.
4. Type del rgstrtn.lck, and then press ENTER.
5. Type dir /b /od /ad, and then press ENTER.
6. Type rd /q /s "<folder names>", and then press ENTER.
   
   Note The <folder names> are the folder names that are listed after you run the command in step 5. There should be a space between each folder-name. For example: rd /q /s "foldername1" "foldername2" "foldername3".
7. Type exit, and then press ENTER.

In Windows Vista and Windows 7

1. Click Start, and then type cmd in the Start Search box, and then click OK.
2. Type cd "%allusersprofile%\Microsoft Help", and then press ENTER,
3. Type attrib -h rgstrtn.lck, and then press ENTER.
4. Type del rgstrtn.lck, and then press ENTER.
5. Type dir /b /od /ad, and then press ENTER.
6. Type rd /q /s "<folder names>", and then press ENTER.
   
   
   Note The <folder names> are the folder names that are listed after you run the command in step 5. There should be a space between each folder-name. For example: rd /q /s "foldername1" "foldername2" "foldername3"
7. Type exit, and then press ENTER.

Thats it!!
Now you can instally any version of Office in your pc. Enjoy!!!!!
