Environment

Windows 2008 R2/XP

Diagnosing the problem

Use Process Monitor to determine if the process Tm1a.exe can find msmask32.ocx.

Also, search the hard drive to confirm whether it exists and is in the correct location.

Resolving the problem

If it has been determined that the file cannot be found, download the file via http://activex.microsoft.com/controls/vb6/msmask32.cab

and place it in the appropriate directory:

Unzip msmask32.cab and place msmask32.inf and msmask32.ocx in C:\Windows\SysWOW64

- For Windows Server 2008, Windows Vista, and Windows 7:
C:\Windows\SysWOW64
- For Windows XP:
C:\Windows\System for WIndows XP

Then, register using the following procedure:

1. Click Start>Run...

2. Type Regsvr32.exe <path>\msmask32.ocx (check for the correct name)
Ensure you have Administrator privileges on the system in order to perform this action.

3. Once the file is registered successfully, try viewing the transaction log.

If problem is not resolved, open a command prompt with the "Run as Administrator" option, then proceed with steos 2 and 3 again.
