Abstract:
|
||
|
|
|
||
|
|
Due to a modification in the registry in Windows XP, this app gets the path
|
||
|
|
for IE as "%programfiles%\ Internet Explorer\iexplore.exe" and since the
|
||
|
|
env variable option flag is not set for ShellExecuteEx, it cannot expand it.
|
||
|
|
Hooked ShellExecuteW also as the app calls this at a few places.
|
||
|
|
|
||
|
|
Notes:
|
||
|
|
|
||
|
|
This is an app specific shim.
