Is it not installing at all, or just not functioning after the install?

If the original version is not installing at all, RealFlight will do a free swap of the full G2 version if you send them the CDs for both the original and the G2 upgrade. I believe that is written on their FAQs page. If not, you can email them to verify.


If it is installing but not functioning, the upgrade requires the original version to be installed on the system, but it does not have to function. I believe the website says to install, but not run, the original version prior to installing the G2 upgrade.

I recently rebuilt the PC I have G2 on. It had Win98. I installed Windows XP Professional. I installed RF Classic. I then installed the G2 upgrade. Then I started G2 using the CD, which gives you the update option. After downloading the updates, I finally started RealFlight and it worked flawlessly.

I had a LOT of issues with G2 the first few times I installed it (last year), one of which ended with a complete system rebuild. In the end, installing both versions and updating BEFORE running is the recipe that has worked consistently for me.
