Developing a launcher that needs multiple registry keys

Submitted by BrianAll on April 3, 2008 - 7:07pm

Okay...
I'm making a launcher for an app that happens to be using 4 different registry keys, and all of them are essential for the program to run. I've been looking at the NSIS script for 7-zip, but it only needs one key. My question is: How do I arrange the script when it is using more than one key? Here is the section I've been working with:

RegistryBackup:
		StrCmp $SECONDARYLAUNCH "true" LaunchAndExit
		;=== Backup the registry
		${registry::KeyExists} "HKEY_CURRENT_USER\Software\7-zip-BackupBy7-ZipPortable" $R0
		StrCmp $R0 "0" RestoreTheKey
		${registry::KeyExists} "HKEY_CURRENT_USER\Software\7-zip" $R0
		StrCmp $R0 "-1" RestoreTheKey
		${registry::MoveKey} "HKEY_CURRENT_USER\Software\7-zip" "HKEY_CURRENT_USER\Software\7-zip-BackupBy7-ZipPortable" $R0
		Sleep 100
		
	RestoreTheKey:
		IfFileExists "$SETTINGSDIRECTORY\7zip_portable.reg" "" LaunchNow
	
		IfFileExists "$WINDIR\system32\reg.exe" "" RestoreTheKey9x
			nsExec::ExecToStack `"$WINDIR\system32\reg.exe" import "$SETTINGSDIRECTORY\7zip_portable.reg"`
			Pop $R0
			StrCmp $R0 '0' LaunchNow ;successfully restored key

	RestoreTheKey9x:
		${registry::RestoreKey} "$SETTINGSDIRECTORY\7zip_portable.reg" $R0
		StrCmp $R0 '0' LaunchNow ;successfully restored key
		StrCpy $FAILEDTORESTOREKEY "true"
	
	LaunchNow:
		Sleep 100
		ExecWait $EXECSTRING

I need to duplicate this for the other keys. Should I just copy it 4 times, or should it be merged together? Can anyone help?
Thanks.

Just do doubles of the same....

All you do is make doubles of the same code, if you told me what your registry keys were i could write it 4 you and give you the code. But make sure it is just the main registry key, not all the sub keys within the main one, like the main one from one of my launchers is HKEY_CURRENT_USER\Software\Piriform while it has a sub key that is HKEY_CURRENT_USER\Software\Piriform\Recuva with all this other stuff.

k the launcher i made recently used to main registry keys, HKEY_LOCAL_MACHINE\SOFTWARE\Piriform and HKEY_CURRENT_USER\Software\Piriform, so here is how i added them, please look closley at what was done, cause after you look at this you should be able to do yours, just yours has 2 more keys than mine did. its a bit long so here it is.....oh yeah i also used 7zip source code for the launcher I made.....

RegistryBackup:
		StrCmp $SECONDARYLAUNCH "true" LaunchAndExit
		;=== Backup the registry
		${registry::KeyExists} "HKEY_LOCAL_MACHINE\SOFTWARE\Piriform" $R0
		StrCmp $R0 "0" RestoreTheKey
		${registry::KeyExists} "HKEY_CURRENT_USER\Software\Piriform" $R0
		StrCmp $R0 "0" RestoreTheKey
		${registry::KeyExists} "HKEY_LOCAL_MACHINE\SOFTWARE\Piriform" $R0
		StrCmp $R0 "-1" RestoreTheKey
		${registry::KeyExists} "HKEY_CURRENT_USER\Software\Piriform" $R0
		StrCmp $R0 "-1" RestoreTheKey
		${registry::MoveKey} "HKEY_LOCAL_MACHINE\SOFTWARE\Piriform" "HKEY_LOCAL_MACHINE\SOFTWARE\Piriform" $R0
		${registry::MoveKey} "HKEY_CURRENT_USER\Software\Piriform" "HKEY_CURRENT_USER\Software\Piriform" $R0
		Sleep 100
		
	RestoreTheKey:
		IfFileExists "$SETTINGSDIRECTORY\Defraggler.reg" "" LaunchNow
	
		IfFileExists "$WINDIR\system32\reg.exe" "" RestoreTheKey9x
			nsExec::ExecToStack `"$WINDIR\system32\reg.exe" import "$SETTINGSDIRECTORY\Defraggler.reg"`
			Pop $R0
			StrCmp $R0 '0' LaunchNow ;successfully restored key

	RestoreTheKey9x:
		${registry::RestoreKey} "$SETTINGSDIRECTORY\Defraggler.reg" $R0
		StrCmp $R0 '0' LaunchNow ;successfully restored key
		StrCpy $FAILEDTORESTOREKEY "true"

Thanks man, I'll give you some credit in the launcher when I finish it. :)

It may be better to keep

It may be better to keep them each seperated, instead of interlocked like that, for example

StrCmp $SECONDARYLAUNCH "true" LaunchAndExit
		;=== Backup the registry
		RegBackup1:
		${registry::KeyExists} "HKEY_CURRENT_USER\Software\Piriform" $R0
		StrCmp $R0 "0" RegBackup2
		${registry::KeyExists} "HKEY_CURRENT_USER\Software\Piriform" $R0
		StrCmp $R0 "-1" RegBackup2
		${registry::MoveKey} "HKEY_CURRENT_USER\Software\Piriform" "HKEY_CURRENT_USER\Software\Piriform" $R0
		Sleep 100
		
		RegBackup2:
		${registry::KeyExists} "HKEY_LOCAL_MACHINE\SOFTWARE\Piriform" $R0
		StrCmp $R0 "0" RestoreTheKey
		${registry::KeyExists} "HKEY_LOCAL_MACHINE\SOFTWARE\Piriform" $R0
		StrCmp $R0 "-1" RestoreTheKey
		${registry::MoveKey} "HKEY_LOCAL_MACHINE\SOFTWARE\Piriform" "HKEY_LOCAL_MACHINE\SOFTWARE\Piriform" $R0
		Sleep 100

This way, if one set of keys fails, the other can still be processed. The the setup listed above, if the very first condition isn't passed, it jumps right to RestoreTheKey, skipping all other reg keys.

Oh yeah dont forget....

Dont forget to do this afterwards, to make sure it works properly. Take your time as it is easy to forget and make mistakes.Also make sure on SetOriginalKeyBack: you add all your keys to delete and Keyexists or they wont be removed.

LaunchNow:
		Sleep 100
		ExecWait $EXECSTRING
		
	CheckRunning:
		Sleep 1000
		FindProcDLL::FindProc "${DEFAULTEXE}"                  
		StrCmp $R0 "1" CheckRunning
		
		StrCmp $FAILEDTORESTOREKEY "true" SetOriginalKeyBack
		${registry::SaveKey} "HKEY_CURRENT_USER\Software\Piriform" "$SETTINGSDIRECTORY\Defraggler.reg" "" $0
		${registry::SaveKey} "HKEY_LOCAL_MACHINE\SOFTWARE\Piriform" "$SETTINGSDIRECTORY\Defraggler.reg" "" $0
		Sleep 100
	
	SetOriginalKeyBack:
		${registry::DeleteKey} "HKEY_CURRENT_USER\Software\Piriform" $R0
		${registry::DeleteKey} "HKEY_LOCAL_MACHINE\SOFTWARE\Piriform" $R0
		Sleep 100
		${registry::KeyExists} "HKEY_CURRENT_USER\Software\Piriform" $R0
		StrCmp $R0 "-1" TheEnd
		${registry::KeyExists} "HKEY_LOCAL_MACHINE\SOFTWARE\Piriform" $R0
		StrCmp $R0 "-1" TheEnd
		${registry::MoveKey} "HKEY_CURRENT_USER\Software\Piriform" "HKEY_CURRENT_USER\Software\Piriform" $R0
		${registry::MoveKey} "HKEY_LOCAL_MACHINE\SOFTWARE\Piriform" "HKEY_LOCAL_MACHINE\SOFTWARE\Piriform" $R0
		Sleep 100
		Goto TheEnd

HKLM is different

John T. Haller (Homepage) - April 4, 2008 - 12:45am

HKLM is a special case. Only an admin account can write to it. Check out the Eraser Portable launcher for example code on handling both HKCU and HKLM and checking for account rights.

Live with purpose.

Yeah I know

BrianAll - April 4, 2008 - 7:31am

I'll check out the source for eraser portable asap.
Thanks.

I just used what Rab040ma gave me. A macro to check if admin, and if it is, it'll do those reg keys.

Somebody give me a portable video editor... Please!
