I just got my 8100 today, and I upgraded BB Desktop Manager to 4.2 with the CD in the box. I rebooted & launched and tried to run the Switch Device Wizard, and got a Visual C++ Runtime error, saying abnormal program termination. I made sure I upgraded from the latest 4.2 version on the BB website too.

Has anyone seen this before?

I would suggest performing a clean uninstall/install of BDM. I can launch it without any problems.

When you get that error, can you move that error message out of the way and let us know where it exactly stops if it gives you a progress bar.

I've done a full clean uninstall/re-install, and I'm getting this error.

What I've discovered is that I get it whenever I click on *anything* in the Desktop Manager, so what I'm wondering is this: What's the Windows OS requirement for 4.2? Is it WinXP? My company is still on Win2K, and I wouldn't be surprised if that was hosing this. Just a thought.

Any other ideas?

Do you get this error with the BlackBerry connected to the computer or disconnected from the computer?

Same result either way...

If the device is disconnected, I get the runtime error as soon as I click on any icon (E-mail Settings, etc). If the device is connected, I get the runtime error as soon as I enter the BB password.

So, the subject (which I don't think will change on the main article) is now better suited as Desktop Manager 4.2 issues... This has nothing to do with the Switch Device Wizard.

I've done multiple uninstalls/reinstalls of the DM software, the latest being a reboot --> uninstall --> reboot --> reinstall --> reboot, with the same result.

I've tried it with my 7100 plugged in, with my 8100 plugged in, and with no device plugged in. I'm getting Visual C++ runtime errors every time.

The latest here is that my co-worker went out & bought an 8100 today also, and he's having the exact same C++ runtime issue that I am.

I'm thinking more and more that the issue is with the build on our laptops.

This happened to me when I installed 4.2 without uninstalling 4.1 first. When you uninstall, make sure that "c:\program files\research in motion\blackberry" and c:\program files\common files\research in motion" are actually deleted. Note that the common files directory contains any updated firmware you might have. Also delete any shortcuts you might have copied to other folders.

Good thoughts, and at this point we've tried them all. In fact, I spent a few hours today being kicked around escalations through 3 different levels of TMo tech support, and then they sent me up to RIM themselves.

At this point, RIM is asking their engineers to attempt to replicate the issue, but everything right now points to it possibly be an incompatibility between Desktop Manager 4.2 and the BES version we're running (2.2.4.6). The RIM tech couldn't say for sure, but we're talking as-new-as-it-gets for DM and pretty old for BES. I've scoured the DM documentation though, and nowhere does it list minimum BES versions required. On this path (and hoping to skip ahead of the up to 72 hours RIM said they'd take to get back to me), I posted in the BES forum here to see if anyone knows.

What I know is this: We've tried DM 4.2 on multiple PC's at our office, with 4 different BB handhelds, and scores of uninstalls/reinstalls (including wiping out registry keys), and if we try the BES install it crashes. If we try the BIS install, the app seems to work.
