Hi,

Which program are you trying to install?

Removing the appropriate registry key from the Registry Editor and re-registering vbscript should have ideally fix the issue.

Follow the steps listed below:

Step 1: Make sure that the Vbscript.dll and Jscript.dll files are not registered in HKEY_CURRENT_USER (HKCU).

a. Click “Start”, type “regedit” in the Start search box and hit “Enter”.

b. Locate the following keys:

VBScript: HKCU\SOFTWARE\Classes\CLSID{ B54F3741-5B07-11CF-A4B0-00AA004A55E8}

Jscript: HKCU\SOFTWARE\Classes\CLSID{ F414C260-6AC0-11CF-B6D1-00AA00BBBB58}

c. Remove these keys if they exist in HKEY_CURRENT_USER.

Registry edit disclaimer:

Important Serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click the following article: **http://windows.microsoft.com/en-US/windows7/Back-up-the-registry**

Step 2: Reregister the Vbscript.dll and Jscript.dll files in the system32 directory from an elevated command prompt by using Regsvr32.exe.

Follow these steps:

a. Click “Start”, type “cmd” in the Start search box and hit “Enter”.

b. Right-click “cmd” and select “Run as administrator”.

c. Type the following commands and press “Enter”:

regsvr32.exe vbscript.dll

regsvr32.exe jscript.dll

I'm not sure I understand all this and the disclaimer bothers me since I am not very computer literate!

I am trying to install a program that reads a data card for my CPAP machine which I use because I have sleep apnea.

I'll check out the answer more thoroughly when I have more time.

Thanks
