Vortex 0.16.8 can't install Skyrim SE mod w/ FOMOD setup: SRX Followers - All-in-One Edition SE

[Paltiel]

Hello! There are two issues in this bug report.
1) Vortex can't install a specific mod with an FOMOD installer. NMM had no problem with this mod.
2) After the install is cancelled, no other mods with FOMOD installers can be installed. Vortex must be restarted to get past the bug that deactivates the installation process next step button.

** Extended Bug Report **
When attempting to install a specific Skyrim SE mod, Vortex won't allow the user to go to the next step. Please see screenshot, below. Selecting either of the two, red-colored options does not activate the dusky orange (Optionals) button.


Please note, Nexus Mod Manager was able to install 'SRX Followers - All-in-One Edition SE' without issue.

Yeah, as far as I can tell that installer is invalid.

You have

<group name="Make sure you install every required mods." type="SelectExactlyOne">

and inside that you have two plugins that are both marked as Required, thus you can't actually select only one because both are force-enabled.

It's simply displayed badly because in the UI a radio button group will only ever show one as selected but internally, both plugins are enabled and can't be disabled.

 

If NMM installs this then that's a bug in NMM, not Vortex.

 

EDIT: Sorry, forgot to reply to the second part of the report. I'll look into it.

EDIT2: Can't reproduce it though, when I cancel that installer and start a different one, that installer has a working next button. Could you maybe provide a screenshot of that problem?

[rmm200]

If you read that mod's comments back aways, it says the FOMOD is invalid for NMM - and to install manually.

No idea why NMM handles it now.

[Tannin42]

I think the installer has been fixed to work with NMM. If I read the comments correctly there was a case of an <image /> tag without path that caused NMM to fail, that doesn't seem to be the case any more.

[Paltiel]

Thank you for jumping on this so quickly!

... and sorry for the delay in responding. That pesky monster called "work" reared its ugly head. The beast has been slain, although it's likely to respawn in two days, on Monday.

 

Fortunately, this is one of those bugs that's 100% repeatable. There was another post recently that mentioned FOMOD installs contained elements from previous FOMOD containing mods: https://forums.nexusmods.com/index.php?/topic/7060626-mod-install-window-contains-text-from-previous-mod-install-window/

I can't help but wonder if these two issues are related; Variables may not be getting correctly cleared (initialized) between mod installs?

Onto the bug report! ^-^

This is after pressing the 'X' button at the top right of Vortex's FOMOD installer, and attempting to install https://www.nexusmods.com/skyrim/mods/73374. Please note the deactivated (Next) option and a stale element still hanging around.

 

After restarting Vortex, (Next) is no longer "greyed out" and several other things load:

 

Finally, a screenshot showing successful installation:
