The cause of this problem occurs when the following *. inf file contain a description of the source media is not correct: * Fp40ext.inf,* Ims.inf

The first step is to make visible the hidden files and then back up two files:
1) In Windows Explorer, choose Folder Options from the Tools menu
2) Click the View tab
3) Hidden files and folders, click Show all files and folders.
4) Open the folder C: \ Windows.Inf.
5) Click on the file Fp40ext.inf, click on Edit and then click Copy.
6) From the Edit menu, click Paste. This creates a copy of the file Fp40ext.inf called Copy of Fp40ext.inf
7) Repeat steps 5 and 6 for the file Ims.inf.

to slove the problem folloe the step:
Start / Run / regedit
when we are in the Register
HKEY_LOCAL_MACHINE \ SOFTWARE \ MICROSOFT \ WINDOWS \ CURRENTVERSION \ SETUP
select it and right key if not already there: "Edit \ New \ String Value and give name as SourcePath
Double-click and return the letter of our CD-ROM for example
D: \
do the same thing in this other location
HKEY_LOCAL_MACHINE \ SOFTWARE \ MICROSOFT \ WindowsNT \ CurrentVersion
select it and right key if not already there "Edit \ New \ String Value and give name as SourcePath
Double click and type the letter of our CD-ROM as we did before. Restart to consolidate the change.

The second step is to modify Fp40ext.inf and Ims.inf:

1) Open the file in Notepad Fp40ext.inf. Fp40ext.inf The file is located in the C: \ Windows.inf.
2) Locate each line that contains the word "Professional"
3) Delete "any application for Professional" and replace it with "Home"
4) Save and close the file Fp40ext.inf.
5) Open the file in Notepad Ims.inf. Ims.inf The file is located in the C: \ Windows.inf.
6) Locate each line that contains the word "Professional"
7) Delete "any application for Professional" and replace it with "Home"
8) Save and close the file Ims.inf.
9) Close the Notepad
