Problem: Microsoft Office Word, Excel, Powerpoint, and Internet Explorer close unexpectedly on a regular basis in Vista. Crash report lists gdiplus.dll_unloaded as the module.
1. gdiplus.dll_unloaded is in conflict with Apple iCloud, uninstall the iCloud program and reboot the machine, this will correct the regular crashes.
2. If you want to maintain iCloud, open Windows Control Panel, find the iCloud control panel icon, open the control panel and allow iCloud to deploy fully to all of the programs on the affected computer. This will result in new icons appearing in Word and Excel.
3. If neither of the above solutions work, or if gdiplus.dll is not listed, try scanning the machine for malware.
