and so it goes... 

"My boss just asked me to justify the cost. I told him that I would pay out of pocket if necessary"

"When I accepted the offer, I specifically said WinDOT had to be part of the package"

"The navigation and functionality is wonderful. Very user friendly. I love that the GPTC Guide and the PHMSA Enforcement Guidance is listed in the Table of Contents; so convenient. The search function is so much faster. So far I love it"

"WinDOT's functionality, ease of use and vast amount of information make it a must have for not only code/compliance engineers but anyone involved in operating gas or liquid pipelines! ViaData has continuously strived to provide a superior product with high levels of customer satisfaction."

Windows Vista and Windows 7 Installation Instructions

When you attempt to open a WinDOT product, you may receive this message:

ViaData LP


If so, you will need to download the WinHelp engine from Microsoft's site since it is not distributed with Vista or Windows 7.  There is also a registry tweak needed that gets handled as part of the process.

The instructions are at

Scroll down to the Blue tab Resolution and click on Download WinHlp32.exe for Windows Vista or Windows7 as appropriate

The Vista/Windows 7 installation will be validated, and then the download can be done.

Choose the download for either the 32-bit or 64-bit as appropriate for your machine.  There are instructions in the article that will tell you how to determine which machine you have. You then chose ***x-64.msu for the 64-bit version or ***x86-msu for the 32-bit version

Go back to the very first screen of the Knowledge Base article and scroll down until you see the blue tab on the left – More information for advanced users

Look for How to enable macros on a single computer after you install the WinHlp32.exe Expand this by selecting Click here to view or hide a detailed automated solution , then click on the Fix It button below and that will do the registry tweak.

Be sure you have done BOTH steps for WinDOT to work properly,
