Erratic event id 1000; Windows Explorer; MSVCR90.dll on Win7 64bit

Question

Windows 7 64 bit. Interacting with Explorer, often as simple as switching to Explorer window and changing focus on a filename. Explorer stops working, generates ID 1000 (see below) and then restarts itself.
Recently installed LibreOffice v 3.6.1.2 and 16-bit Java 6 update 30 (which works with LibreOffice).
I suppose you are going to tell me to uninstall the LO and Java. I'm really hoping for other troubleshooting or diagnostic options. The LO and java setup is for a project of some urgency.

Hi,
According to the event log, we can see that the issue is related to MSVCR90.dll.
Therefore, please use ShellExView to disable this extension of Windows Explorer:
1) Please download
ShellExView for x64-bit system.
Note: The third-party product discussed here is manufactured by a company that is independent of Microsoft. We make no warranty, implied or otherwise, regarding this product's performance
or reliability.
2) Extract the download file and double-click the "shexview.exe" file. It will scan the registry for all the shell extensions.
3) Select the MSVCR90.dll in pink.
4) Click the "Disable Selected Items" on the toolbar and click Yes.
5) Restart your computer and check if the issue is resolved.
If Windows Explorer can work properly after disabling MSVCR90.dll, we can conclude that the issue is caused by LibreOffice. Therefore, please update LibreOffice to the latest or you may have to contact
LibreOffice for help.
Hope this helps.
