I am having problems with the download of gCADPlus

Files with the extension .exe (like gCADPlusSetup.exe) may not be allowed through the firewall of your computer. You can sometimes allow a 'one time' passage of an exe through the firewall by running the virus protection control panel.

A better solution might be to download the zip version of the installation program. Zip files are often passed through firewalls without problems.

Note: We have had our software cleared by the vendors of some virus protection software, but not all vendors have incorporated our software into their exception list.

Download gCADPlusSetup.exe is ok, but the Installation is blocked by virus protection

Perhaps the simplest approach is to remove your computer from the Internet (remove the cable or turn off wireless the wireless connect facility) then DISABLE whatever virus protection software you are running try running the gCADPlus application again. Most times it will install. If successful, start virus protection again and plug in to the Internet. All should be fine.

Application will not run

If the installation program will not run, you may have to tell your virus protection software to allow an exception. Here is some information on specific virus protection products.
