Hi, Sorry it is a long procedure but it should fix your problem.

Perform the steps outlined in each method below (as needed) to restore a damaged registry.
 
Using Real-Mode Registry Editor
-------------------------------
 
WARNING: Using Registry Editor incorrectly can cause serious problems that may require you to reinstall Windows 95. Microsoft cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved.
Use Registry Editor at your own risk.
 
Use Registry Editor in real mode to export, then import, the registry file.
To do so, follow these steps:
 
1. Restart the computer. When you see the "Starting Windows 95" message,press the F8 key, then choose "Safe mode command prompt only" from the Startup menu.
 
2. Type the following line to export the registry
 
      regedit /l:<path1> /e <path2>system.txt
 
   where <path1> is the path to the System.dat file and <path2> is the path to the destination file. For example, if Windows 95 is installed in the Windows folder on drive C, type the following line:
 
      regedit /l:c:\windows\system.dat /e c:\system.txt
 
3. Type the following lines, pressing ENTER after each line:
 
      cd\windows
      attrib -s -h -r system.dat
 
4. Type the following line to rename the current registry file:
 
      ren system.dat system.old
 
5. Type the following line to import the System.dat portion of the registry
 
      regedit /l:<path1> /c <path2>system.txt
 
   where <path1> is the path to the System.dat file and <path2> is the path containing the file to import. For example, if Windows 95 is installed in the Windows folder on drive C and you want to import the System.txt file from the root folder of drive C,
   type:
 
      regedit /l:c:\windows\system.dat /c c:\system.txt
 
   NOTE: If an "Unable to open registry" or "Error accessing the registry" error message is displayed when you attempt to import the System.dat portion of the registry, please see the following article in the Microsoft Knowledge Base for more information about the error  message:
 
ARTICLE-ID: Q132064
TITLE:Regedit May Not Be Able to Import Registry with Large Keys
 
6. Restart Windows 95 normally.
 
If the error continues to occur, follow these steps:
 
  1. Restart the computer. When you see the "Starting Windows 95" message, press the F8 key, and then choose "Safe mode command prompt only" from the Startup menu.
 
  2. Type the following line to export the User.dat portion of the
     registry
 
        regedit /r:<path1> /e <path2>user.txt
 
     where <path1> is the path to the User.dat file and <path2> is the path to the destination file. For example, if Windows 95 is installed in the Windows folder on drive C, type the following line:
 
        regedit /r:c:\windows\user.dat /e c:\user.txt
 
  3. Type the following lines, pressing ENTER after each line:
 
        cd\windows
        attrib -s -h -r user.dat
 
  4. Type the following line to rename the User.dat file:
 
        ren user.dat user.old
 
  5. Type the following line to import the User.dat portion of the
     registry
 
        regedit /r:<path1> /c <path2>user.txt
 
     where <path1> is the path to the User.dat file and <path2> is the path containing the file to import. For example, if Windows 95 is installed in the Windows folder on drive C and you want to import the User.txt file from the root folder of drive C, type:
 
        regedit /r:c:\windows\user.dat /c c:\user.txt
 
     
  6. Restart Windows 95 normally.
 
If the error continues to occur after you follow the steps in this section, please see the next section.
 
Using System.da0
----------------
 
Restore the registry to its state when you last successfully started Windows 95. To do so, follow these steps:
 
1. Restart the computer. When you see the "Starting Windows 95" message, press the F8 key, then choose "Safe mode command prompt only" from the Startup menu.
 
2. Type the following command to move to the Windows folder
 
      cd \<windows>
 
   where <windows> is the Windows 95 folder. For example, if Windows95 is installed in the Windows folder, type the following line:
      cd \windows
 
3. Type the following line:
 
      attrib -s -h -r system.dat
 
4. Type the following line:
 
      ren system.dat system.bad
 
5. Restart your computer. Windows 95 uses the System.da0 file
   when it cannot find the System.dat file. If this file works,
   Windows 95 renames it to System.dat.
 
If the error continues to occur after you follow the steps in this section, please see the next section.
 
Using System.1st
----------------
 
Restore the registry to its state when you first started Windows 95 successfully. To do so, follow these steps:
 
1. Restart the computer. When you see the "Starting Windows 95" message, press the F8 key, then choose "Safe mode command prompt only" from the Startup menu.
 
2. Type the following command to move to the Windows folder
 
      cd \<windows>
 
   where <windows> is the Windows 95 folder. For example, if
   Windows 95 is installed in the Windows folder, type the following line:
 
      cd \windows
 
3. Type the following line:
 
      attrib -s -h -r system.dat
 
4. Type the following line:
 
      ren system.dat system.xxx
 
5. Type the following line:
 
      cd \
 
6. Type the following line:
 
      attrib -s -h -r system.1st
 
7. Type the following line
 
      copy system.1st c:\<windows>\system.dat
 
   where <windows> is your Windows 95 folder.
 
8. Type the following line:
 
      attrib +s +h +r system.1st
 
9. Restart your computer.
 
If the error continues to occur after you follow the steps in this
section, please see the next section.
 
Reinstalling Windows 95
-----------------------
 
Re-create the registry files by reinstalling Windows 95.
 
To do this, perform the following steps.
 
NOTE: If you cannot access the CD-ROM drive from the command prompt, consult the CD-ROM drive's documentation or manufacturer for assistance with loading the real-mode drivers for the CD-ROM drive.
 
1. Restart the computer. When you see the "Starting Windows 95" message, press the F8 key, then choose Command Prompt Only from the Startup menu.
 
2. Type the following line and then press ENTER to remove all user profiles:
 
      deltree c:\windows\profiles
 
3. Rename the existing registry files by typing the following lines.
   Press ENTER after each line:
 
      cd \windows
      attrib -s -h -r system.dat
      ren system.dat system.xxx
      attrib -s -h -r user.dat
      ren user.dat user.xxx
      attrib -s -h -r system.da0
      ren system.da0 system.yyy
      attrib -s -h -r user.da0
      ren user.da0 user.yyy
      cd \
      attrib -s -h -r system.1st
      ren system.1st system.zzz
 
4. Run Windows 95 Setup.
