Which fixture library for Pearl Expert with Titan

[gis]

Hi,
I'm running Titan 8.3 on old Pearl Expert.
To update the fixture library should I download the TitanFixtureLibrary.exe or can I use the CompactTitanFixtureLibrary.exe?

Thanks!

There is no such version as 8.3 but for anything below 10.0 you can use the compact version. Note that you should be able to install v9.1 without any additional hardware requirements. Is there a reason why you have not updated?

Sorry, I mean 8.1.

I didn't upgrade since the system slowed down from Titan 6 to 8 and I didn't have the time to install and check 9.3 (we use it rarely, so no small acts where we can "miss" something. Main systems are on Titan 10.1).

Thanks for your fast reply!
