Using both Pyrevit 4.8.16 and 5.0

[RicWeber]

I have downloaded and installed both versions 4.8.16 and the WIP 5.0. I installed them to two different folders.

I tried to install just the 5.0 hoping it would work with all versions, but I get an error in the pre-2025 versions and it won’t load. So I then try to load up both, but I can’t seem to get them both to work at the same time. Which ever one I reinstall last is the one that seems to work.

Please let me know if this just isn’t meant to work, if I should only have the 5.0 WIP version on the system, or what? If you need more info, let me know. I can get screenshots for you.

[tayOthman]

can you confirm that the error you get on 2023-2024 is similar to the issue logged here?

[Bug]: Can't run C# pushbutton

The Expectation is to be able to use Pyrevit 5 across all versions, please download the installer from the action below and install, it should fix it for now:

[Jean-Marc (Jean-Marc Couffin)]

I fixed the link as it was a duplicate issue.
The fix is being treated. Expect a new WIP today or monday.
Sit tight.

[RicWeber]

@tayOthman, I did not take screenshots (which I should have, sorry) but those errors do look familiar, so I think that was one of the issues. That link that you provided however, downloads version 5.0.0.24236. I already had 5.0.0.24242, which would be newer correct? @Jean-Marc says he is going to put out a new WIP today or tomorrow, so I’ll wait for that one. Thank you.

[RicWeber]

@Jean-Marc, thank you. I look forward to getting the updated file. Once I get that, I presume I should completely wipe off all older versions of pyRevit from the system, and then install the new. Could you post a link here in this topic once you have it please? Thank you!

[RicWeber]

@Jean-Marc and @tayOthman, I downloaded the new WIP file this morning and got version 5.0.0.24246. I uninstalled all versions of pyRevit from my system. Installed the admin_signed version of 5.0.0.24246. It works in 2025, but not earlier versions. I took a screenshot of the error and pasted it here. I hope this works. Thanks for the new WIP, but it looks like I’m back to 4.8.16.24121 for the moment. I’ll keep my eyes out for updates. Thanks for all of your hard work!

give it a couple of days.

[RicWeber]

@tayOthman Thank you! I saw that there was a new version number, so I figured that was the update @Jean-Marc was talking about. I will wait a couple more days! Thank you!

[Jean-Marc (Jean-Marc Couffin)]

@tayOthman

couple of days.

You will have to be a tad more generous

[tayOthman]

@RicWeber

couple more days

Couple != handful !=Bunch != Two

[RicWeber]

@Jean-Marc and @tayOthman, I downloaded the new WIP file this morning and got version 5.0.0.24254. I uninstalled all versions of pyRevit from my system. Installed the admin_signed version of 5.0.0.24254.
It works in 2025 but a couple of the tools that I tested had errors which I’ll include in the next replies.
Earlier versions of Revit have the same error as a week ago. Thanks for the new WIP, but it looks like I’m back to 4.8.16.24121 for the moment. I’ll keep my eyes out for updates. Thanks for all of your hard work!

This one “works” on all versions

Merge pull request #2357 from pyrevitlabs/fix_hyperlinkengine-test

[RicWeber]

@Jean-Marc, what do you mean by ““works” on all versions”? Do you mean all the apps work fine in 2021-2024, and perhaps some of the apps in 2025?

Also, why would an older version 5.0.0.24229 work better than a newer version 5.0.0.24254?

[Jean-Marc (Jean-Marc Couffin)]

Some of the latest changes (since August 16th) broke some of the things that were working previously.
This version works (launches and display tools) from 2017-2025 and some stuffs are not fixed yet but it is bearable imho

[RicWeber]

@Jean-Marc thank you! That definitely seems to be working better. No errors upon start up in any of the versions. I have not had a chance to test everything yet, so basically just one question: Are all of the tools working in versions 2021-2024?

[Jean-Marc (Jean-Marc Couffin)]

@RicWeber

Are all of the tools working in versions 2021-2024?

yes, they haven’t been changed

I tried to install just the 5.0 hoping it would work with all versions, but I get an error in the pre-2025 versions and it won’t load. So I then try to load up both, but I can’t seem to get them both to work at the same time. Which ever one I reinstall last is the one that seems to work.

FYI if you want to use 4.8.16 for <2024 and 5.0 for 2025, after installing each in separate folders, using the command line:
add the clone if necessary using

path\to\4.6\pyrevit.exe clones add this <clone_name>
path\to\4.6\pyrevit.exe attach <clone_name> default 2020
path\to\4.6\pyrevit.exe attach <clone_name> default 2021
path\to\4.6\pyrevit.exe attach <clone_name> default 2022
path\to\4.6\pyrevit.exe attach <clone_name> default 2023
path\to\4.6\pyrevit.exe attach <clone_name> default 2024

and then for previt 5.0:

path\to\5.0\pyrevit.exe clones add this <clone_name>
path\to\5.0\pyrevit.exe attach <clone_name> default 2025

if you try and attach the older versions using the new pyrevit.exe, it will show “?” for the engine version and fail to load.
Here is my attachments when checked using 4.8.16 pyrevit.exe. Note the question marks for the engine version for 2025:

and this is how the exact same setup looks when checking with the pyrevit.exe from 5.0. Now the ? shows for everything except 2025

[InkRF_WasTooShort (Justin)]

What version of the CLI were you using to attach the different versions of pyRevit to Revit? I’m trying to go this route but it seems that the V4.8.15 of the CLI attaches pyRevits differently to Revit than how V5 of the CLI attaches pyRevits to Revit.

For example, when I go to attach pyRevit V5 (specifically 5.0.0.24255) to Revit 2025 using v4.8.16 of the CLI, I get the following popup when I launch Revit '25:

When attaching pyRevit v4.8.16 Revit 2023 (and other <2025 versions) using the v4.8.16, it works fine.

On the other hand, when I go to attach pyRevit v4.8.16 to Revit 2023 (and other <2025 versions) using the V5 CLI, I get the below error when launching Revit.

And when attaching pyRevit V5 to Revit 2025 with the V5 CLI, it works fine.
