Nine times out of 10 any error that occurs when trying to run WinBidPro v15 is something that can be fixed by installing the latest version of the program.
Go to gdsestmating.com and click the Products-Downloads link at the top and you will be able to download and install the latest version.
Please note that your Windows user account will need to have "Administrative" rights in order for our software to install correctly. If your company has an IT person that usually installs software and makes changes to your computer, you will want to have that person install the WinBidPro software.
The installer will remove any older version of the software and then install the latest version. If this does not solve your problem, another thing to make sure of is that all of the Windows updates have been installed. If you are not sure if your computer is up-to-date, you can click the Windows icon at the bottom left of your screen and type in "Check for Updates". We recommend installing any updates that are needed.
If none of this solves your problem with GDS, be sure to submit a support ticket so that we may assist you.
