I installed Visual Studio 2013 Professional as a Trial version while waiting for my company to complete the license purchase. They completed the purchase of 4 licenses (64 bit), but were not given Product Keys. Instead, there is a particular file with the license or product key embedded in some way. I want to avoid having to uninstall Visual Studio 2013 only to reinstall Visual Studio 2013 and re-setup all my settings. Is this possible? Is there a way to extract the license/product key from the or from other coworkers desktops that did a clean install. Here is what I have tried (with 2 coworker installations. Looking for the license info in. but it is unique on both computers. Looking for the Product Key in. One install had one, which my install said was invalid when attempting to use it. The other install had a blank PIDKEY. Looking inside but I see no mention of a License or Product Key. Checking their Help Register Product in Visual Studio, which simply says. License: Product key applied. Tried doing an install/repair from the ISO but it says. The product version that you are trying to set up is earlier than the version already installed on this computer. Again, I would really like to avoid the multi-hour process of reinstalling VS 2013. Is there any way. I solved this, without having to completely reinstall Visual Studio 2013.

If you get the error below, you need to update the Windows Registry to trick the installer into thinking you still have the base version. If you don't get this error, skip to step 3. Click the link for 'examine the log file' and look near the bottom of the log, for this line. open and do an Edit Find. for that GUID. In my case it was . This was found in. Edit the BundleVersion value and change it to a lower version. I changed mine from 12.0.21005.13 to 12.0.21000.13. Exit the registry. Run the ISO (or ) again. If it has a repair button like the image below, you can skip to step 4. Otherwise you have to let the installer fix the registry. I did this by "installing" at least one feature, even though I think I already had all features (they were not detected). This took about 20 minutes. Run the ISO (or ) again. This time repair should be visible. Click Repair and let it update your installation and apply its embedded license key. This took about 20 minutes. Now when you run Visual Studio 2013, it should indicate that a license key was applied, under Help Register Product. Hope this helps somebody in the future.
