I managed to crash my LabVIEW 2025 Q3 after Viewpoint TSVN toolkit install

[Xonmyth]

Hello, 

I am in a wee bit of a problem here, hehe. I was exploring the Tortoise SVN, it installed fine and then I found this video and installed the Viewpoint TSVN Toolkit v1.8.5.45 by Viewpoint Systems, Inc.

Post toolkit install, LabVIEW tried to open up as expected but stopped responding on toolkit's dialog screen. I do not have access to the welcome screen or any VIs.

I gave this several tries but every time I would have to force close the application. Tried system restart, running it as admin and a bit of fooling around with the LabVIEW.ini file with no success. 

Now, the problem is that I cannot uninstall it using VIPM 🙂 as it  also tried to connect with LabVIEW and then gets stuck on the same screen. 

Any suggestion other than fresh install is much appreciated. 🙂

I feel like a Broken Record (thanks, Windows 11 and LabVIEW 2025).

First, I would get in touch with Viewpoint Systems and explain your problem.  You can contact them directly from their Web Site (www.viewpointusa.com).  When I left Rochester (where they are located) 8 years ago, they were very friendly folks, who hosted the (infrequent) meetings of a LabVIEW User Group.  They may know about this problem, and have a "repair" procedure for you.

If you want to "do it yourself", the fastest and safest (possibly the only safe method) is to do the following steps:

1. Using Control Panel, Programs and Features, uninstall NI Software.  Be sure you don't have "Products Only" checked.  Click the "Name" box on the left to select everything (except NI Package Manager, greyed out by default).  This gets rid of almost everything.  Reboot.
2. Do it again.  This time, (but see step 3) it might only show NI Package Manager.  That's OK.  Proceed, and remove NIPM.  Reboot.
3. Do it a third time.  You might see some software associated (perhaps) with older versions of LabVIEW, pre-NIPM.  Remove and reboot.
4. Now you are ready to reinstall LabVIEW 2025 (and VIPM).  I recommend you only install components and drivers that you know you need now.

Note that a "Repair" operation usually takes much longer, as does a "partial removal" (for example, to uninstall only LabVIEW 2019, for example).

I've been using Tortoise SVN for almost two decades.  I recall trying the Viewpoint toolkit, but I only used it briefly.  I find Tortoise SVN easy enough to use (I'm a very small "shop") and the Tortoise help sufficient for my needs.

Many thanks Bob_Schor!

I will follow you second suggestions first and then the first as I think your second suggestion will at least get me backup and running quicker. 

However, since I will be re-installing anyways, I am really curious to see what will happen if I just delete Viewpoint files from the vi.lib folder. If you think it will not result into a fatal crash or everlasting registry issues, I am more than willing to give that a try. (I would still follow your steps this is just a curiosity)

Do you think it is worth the try 😃?
