UserMgr plugin question

What I need to do, is from the installer, place some entries into a specific user's registry settings. I tried this example I found from the web (below). It always dies with error 3 on the RegLoadUserHive.

Section User
UserMgr::CreateAccountEx "myuserA" "mypassword" "A test user created by the UserMgr plugin" "My User A" "A test user created by the UserMgr plugin" "UF_PASSWD_NOTREQD|UF_DONT_EXPIRE_PASSWD"
Pop $0
MessageBox MB_OK "CreateUser Result : $0"

UserMgr::BuiltAccountEnv "myuserA" "mypassword"
Pop $0
MessageBox MB_OK "BuiltAccountEnv Result : $0"

UserMgr::RegLoadUserHive "myuserA"
Pop $0
MessageBox MB_OK "RegLoadUserHive Result : $0"

WriteRegStr HKEY_USERS "myuserA\Software\My Company\My Software" "String Value" "dead beef"

UserMgr::RegUnLoadUserHive "myuserA"
Pop $0
MessageBox MB_OK "RegUnLoadUserHive Result : $0"
SectionEnd

Digging further... even though the command returns success.. The Build Account Environment does not seem to be creating an entry in the registry HKEY_USERS either.

Does it create a user? Is there a ntuser.dat file in the profile folder?

Yes. The user is good. The Build Env return success.

If I do this stuff from the Command line with Reg load and Reg add it works, but I'd rather use nsis.

Which Windows version is this?

I just tried this on a fresh Windows 2000 install (why not) and BuiltAccountEnv fails with error 1314 (when calling LogonUser) but RegLoadUserHive works and is able to write the value.

I guess my problem comes from https://support.microsoft.com/en-us/...ting-systems#: "The first and biggest of these restrictions is that on Windows NT and Windows 2000, the process that is calling LogonUser must have the SE_TCB_NAME privilege (in User Manager, this is the "Act as part of the Operating System" right)."

Windows 10.

It works fine on XP for me if I add a call to UserMgr::AddToGroup:

UserMgr::CreateAccountEx "myuserA" "mypassword" "A test user created by the UserMgr plugin" "My User A" "A test user created by the UserMgr plugin" "UF_PASSWD_NOTREQD|UF_DONT_EXPIRE_PASSWD"
Pop $0
DetailPrint "CreateUser Result : $0"
UserMgr::AddToGroup  "myuserA" "Users"
Pop $0
DetailPrint AddToGroup=$0
UserMgr::BuiltAccountEnv "myuserA" "mypassword"
Pop $0
DetailPrint "BuiltAccountEnv Result : $0"
UserMgr::RegLoadUserHive "myuserA"
Pop $0
DetailPrint "RegLoadUserHive Result : $0"
WriteRegStr HKEY_USERS "myuserA\Software\My Company\My Software" "String Value" "dead beef"
MessageBox mb_ok "Check in Regedit but remember to close Regedit again so the key is not held open!"
UserMgr::RegUnLoadUserHive "myuserA"
Pop $0
DetailPrint "RegUnLoadUserHive Result : $0" 

* CreateAccountEx calls NetUserAdd(USER_INFO_2)
* BuiltAccountEnv calls LogonUser+LoadUserProfile+UnloadUserProfile (This creates the profile directory and probably the ntuser.dat file but it does not load it into HKEY_USERS)
* RegLoadUserHive calls RegLoadKey after finding the path to ntuser.dat in ProfileList

If this does not work for you then perhaps you should try contacting the plug-in author for support, it was probably never tested on Windows 10.
