Looks like a TYPO in a plugin.
The application or DLL \??\e:\i386\system32\RPCT4.DLL is not a valid windows image.
Normally this command would be \\?\E:\i386\.... or \\??\\E:\i386\...
This is a workaround for limited pathname length.
If this is for a driver plugin following IMAGEPATH, you don't need the drive letter.
Look at this example taken from an early version of bootskin plugin.
Finding the error...
Right click on your PLUGINS directory & choose SEARCH.
In the TEXT SEARCH BOX(not files box) enter RPCT4.DLL.
This will let you know what plugin is causing the problem.
Make sure you post back with what it was, as i'm sure someone else has this plugin also.
