Q: Unable to open H2 Viewer error saying 'MS Help 2.x runtime not found' This thread is locked from future replies

I have installed H2 Viewer; however when I try to open the application I get an error saying 'MS Help 2.x runtime not found'. How do I resolve this if I'm using Windows 7 OS?



Hi Shyama_N,


I’d recommend you uninstall and reinstall the program in compatibility mode and see if that fixes the issue.

To install the program in compatibility mode, refer the following article:


Make older programs run in this version of Windows


Reinstall the program in administrator mode. Follow these steps:


a.     Locate the program icon, right-click and select as “Run as administrator”.

b.     When the User Account Control (UAC) message is displayed, do one of the following:


-       If you are logged on as a standard user, or if UAC is configured to always require credentials, enter the appropriate administrative credentials, and then click OK.

-       If you are logged on as an administrator and UAC is not configured to always require credentials, click “Yes” to start the application.


c.     Proceed with the installation and see if the issue gets fixed.
