IBM Iseries will not start or uninstall after removing Lenovo bloatware from a T61

I have a user that recently complained of slow system performance. I removed PC-Doctor and all of the proprietary Lenovo software from his laptop. Then, I-Seires would not start. I opened control panel to remove it, and get a CA400RES.DLL dialog, which says only CWBNL0202- [two characters that are displayed as squares]\CA400RES.DLL.

If I remove "CA400.CPL.CPL" from c:\Windows\System32, the error quits, which suggests the Iseries plugin isn't loading properly.

I've reinstalled 5.7 over the network to no avail. Anyone have any idea what might fix this issue?

Lenovo software doesn't generally cause slow performance (I have a T61p Thinkpad and I have most Lenovo software installed). I wonder if you removed some software that the T61 needs to run.

Is it possible using Windows Restore Point to return back to a working point?  If so, then look at temporary files, fragmentation (defrag it), memory (SP3 needs at least 1 Gb of memory and preferably more). Also consider the possibility of viruses and other malware.

Ultimately, if you cannot restore to working condition, it may just be simply faster to reimage and start again. ... Thinkpads_User

We have system restore disabled by policy, so that's a no-go. The user has another machine he can use so reimaging is not out of the question.

Somehow in the removal process, some of the Client Access installation got crushed or registry corrupted.  If reinstalling didn't work, I'd just re-image, clean up (if needed), and then install CA.

Yeah, I don't have a magic bullet for you here, and with this kind of thing I don't trust the config after that anyway.  Usually saves time to just reimage.
