Error: Could not access VBscript run time for custom action.

Recently got an update from the application team that they are unable to install and software. When executing the setup file they are getting an error pop-up window stating “Could not access VBscript run time for custom action.”. This issue was fixed using below steps:

1. Open Registry Editor” and locate the below key.

HKEY_Local_Machine\SOFTWARE\Classes\CLSID\{B54F3741-5B07-11CF-A4B0-00AA004A55E8}

2. Expand {B54F3741-5B07-11CF-A4B0-00AA004A55E8} key, locate InprocServer32 and click on it.
In the right column you should see two values.

3. Right-click InprocServer32 > Permissions > Advanced > Permissions > highlight Administrators, choose Edit > and in the Permissions check box next to Full Control; Save all changes;

4. Then in the right column or Registry Editor right-click (Default) > Modify, and insert the correct path in Value Data:

C:/Windows/system32/vbscript.dll

5. If you have 64-bit Windows repeat steps 3 – 5 for next registry keys:

HKEY_Local_Machine\SOFTWARE\Classes\Wow6432Node\CLSID\{B54F3741-5B07-11CF-A4B0-00AA004A55E8}

HKEY_Local_Machine\SOFTWARE\Wow6432Node\Classes\CLSID\{B54F3741-5B07-11CF-A4B0-00AA004A55E8

6. After that close Registry Editor.

After the above changes when we tried executing the same setup it went success.
