Two versions of Affinity Photo at the same time?


Recommended Posts

Hello @Henrik Caspersen, and welcome to the forums.

You can install two separate versions of Affinity provided that you install them in two separate directories.

Are you sure?

On Windows, some of the data will always end up in

  • C:\ProgramData\Affinity\Photo\1.0 and a bunch more will always end up in
  • C:\Users\<username>\AppData\Roaming\Affinity\Photo\1.0

If you install two releases the data for the second one will overwrite the data for the first one, and especially for the items in AppData that will be disastrous if you use the wrong level of the program.

I asked this question myself a few versions back. I was advised by a staff member that I could do so. I installed 1.6 in a separate directory, and I have had no trouble with it.

However I do take your point.

If I try to install the 1.9.2 version I get a "Affinity Photo will be updated to version 1.9.2" message. I can't even choose another directory. 

Right, and that's exactly what's supposed to happen.

If you wanted to have two versions available you would need to play some games. For example, I think this would work:

  1. Install 1.8.5.
  2. Copy C:\Program Files\Affinity\Photo to (say) C:\Program Files\Affinity\Photo185
  3. Copy C:\ProgramData\Affinity\Photo to C:\ProgramData\Affinity\Photo185
  4. Copy %AppData%\Affinity\Photo to %AppData%\Affinity\Photo185
  5. Install 1.9.2, which will update 1.8.5.

Then, you would be running 1.9.2. If you ever want to run 1.8.5, you would:

  1. Rename C:\Program Files\Affinity\Photo to C:\Program Files\Affinity\Photo192
  2. Rename C:\ProgramData\Affinity\Photo to C:\ProgramData\Affinity\Photo192
  3. Rename %AppData%\Affinity\Photo to %AppData%\Affinity\Photo192
  4. Rename C:\Program Files\Affinity\Photo185 to C:\Program Files\Affinity\Photo
  5. Rename C:\ProgramData\Affinity\Photo185 to C:\ProgramData\Affinity\Photo
  6. Rename %AppData%\Affinity\Photo185 to %AppData%\Affinity\Photo

To switch back to 1.9.2 would be a very similar procedure.

(And, of course, one could create a .bat file or some other scripting file to make all the renaming back and forth simpler and safer.)

The only way I could see that working is if you also installed it under a different Windows user ID. That would at least handle the conflicts with %AppData%. I suspect that the conflicts with ProgramData would not cause much (if any) harm.

The 1.9 seems to be extremely prone to crashing.

Do you have Hardware Acceleration enabled in Preferences/Performance? If so you might disable it for now.

I don't think so. Do I?

No, but you don't seem to have 1.9 installed either, from that screenshot.

So I'm not sure that you can be sure that, for you, it would be prone to crashing.

Is it possible to have two versions of Affinity Photo on my computer, say the 1.8.5 and 1.9?

Yes, I have versions 1.6, 1.7, 1.8, and 1.9 all available on my PC but only one can be active at a time and each time you run a particular version all user defaults are lost or reset to that version.

An easier option for you is to have 1.8.5 installed and also have installed the last beta version of 1.9.2. They will not conflict with each other and you can additionally run them both at the same time, if needed.

Thats true. It's 1.8.5.  I can hardly keep the 1.9 going for more than a few minuttes at a time before it will crash! I assume from you reply that Hardware Acceleration is something new in 1.9, yes?

Yes, hardware acceleration is new in 1.9.

You need to switch that off if you are experiencing crashes as it's known to do that in certain PC configurations. (So that's the first thing to try)

To save time I am currently using an automated AI to reply to some posts on this forum. If any of "my" posts are wrong or appear to be total b*ll*cks they are the ones generated by the AI. If correct they were probably mine. I apologise for any mistakes made by my AI - I'm sure it will improve with time.
