When using the Flex Profile Kit/Flex Framework the following error may be caused during logon:

Event Type: Error
Event Source: Application Error
Event Category: (100)
Event ID: 1000
Description: Faulting application FlexRefresh.exe, version 0.0.0.0, faulting module FlexRefresh.exe, version 0.0.0.0, fault address 0x00002cdf.

This does not appear to happen consistently, or when the application is run interactively.

Ensure the user profile/Default Profile has all of the following registry keys:

[HKEY_CURRENT_USER\Control Panel\Colors]
"ActiveBorder"="212 208 200"
"ActiveTitle"="10 36 106"
"AppWorkSpace"="128 128 128"
"Background"="58 110 165"

"ButtonFace"="212 208 200"
"ButtonHilight"="255 255 255"

The last two were found to be missing. To add these the Default User profile:

SET LoadKey=DefaultUser
REG LOAD "HKU\%LoadKey%" "%SystemRoot%\Documents and Settings\Default User\NTUSER.DAT"
Rem Fix FlexRefresh Application Error
REG ADD "HKU\%LoadKey%\Control Panel\Colors" /t REG_SZ /v MenuHilight /d "210 210 255" /f
REG ADD "HKU\%LoadKey%\Control Panel\Colors" /t REG_SZ /v MenuBar /d "212 208 200" /f
