Hello! Today I've decided to try Nebula3 Free. I've downloaded Nebula3 Free x64 version and properly installed it. Whenever I try to run it in FL Studio 9, following error message appears: The application or DLL C:\Program Files\VstPlugins\acustica\Nebula3Free.dll is not a valid Windows image. Please check this against your installation diskette.
Same thing happens with Nebula3 Free Reverb. In order to fix this problem I removed Nebula3 Free and installed it again from a new file that I downloaded. Nothing resolved the problem.
Sorry, but I'm not familiar with any other DAW than FL Studio. If it's important, I can get a demo copy of Reaper and try out. Also I forgot to mention that I had installed Nebula on this PC couple of months ago (can't remember which version). I had it for couple of hours on my PC and removed it, because I was lazy to figure out how to work with it.
I've followed your instructions. In Options > Preferences > VST I've added the following folder C:\Program Files\VstPlugins\acustica and then I went to FX on the track but I couldn't find the Nebula3. Right after that I've shutted down Reaper and started it up again. As soon as Reaper started up, I got the same message. First for Nebula3 Free and then for Nebula3 Free Reverb.
I've found the root of this seemingly complicated problem. Surprisingly, the problem was simple. I was trying to install Nebula3 Free x64 version on my 32 bit platform. I want to apologize for taking your time in resolving such an obvious problem. Also I would like to thank you for your help.
