DLL register / unregister
Hi, please help me with this problem.

Some my applications use the same SHARED DLL and/or OCX:

-installing one or more of them, Reg Counters seems NOT change (i found the same values after each installation)
- the first application I un-install CLEAR all REG Values (de-register) and delete the DLL

Here my code

Section /o "Vr Client" SecClient

StrCpy $Version 0
ReadRegDWord $Version ${UMUI_PARAMS_REGISTRY_ROOT} "${UMUI_PARAMS_REGISTRY_KEY}" "VR CLIENT"

StrCmp $Version 1 ClientOLD ClientNEW
ClientNEW:
StrCpy $ALREADY_INSTALLED 0
Goto ClientSTOP
ClientOLD:
StrCpy $ALREADY_INSTALLED 1
Goto ClientSTOP
ClientSTOP:
Nop

!insertmacro InstallLib REGDLL $ALREADY_INSTALLED REBOOT_PROTECTED \
"Client\Support\XPCONTROLS.OCX" "$SysDir\XPCONTROLS.OCX" "$SysDir"


WriteRegDWord ${UMUI_PARAMS_REGISTRY_ROOT} "${UMUI_PARAMS_REGISTRY_KEY}" "VR CLIENT" 1

SectionEnd

Section /o "Vr Sportello" SecSportello

StrCpy $Version 0
ReadRegDWord $Version ${UMUI_PARAMS_REGISTRY_ROOT} "${UMUI_PARAMS_REGISTRY_KEY}" "VR SPORTELLO"

StrCmp $Version 1 SportelloOLD SportelloNEW
SportelloNEW:
StrCpy $ALREADY_INSTALLED 0
Goto SportelloSTOP
SportelloOLD:
StrCpy $ALREADY_INSTALLED 1
Goto SportelloSTOP
SportelloSTOP:
Nop


!insertmacro InstallLib REGDLL $ALREADY_INSTALLED REBOOT_PROTECTED \
"Sportello\Support\XPCONTROLS.OCX" "$SysDir\XPCONTROLS.OCX" "$SysDir"

WriteRegDWord ${UMUI_PARAMS_REGISTRY_ROOT} "${UMUI_PARAMS_REGISTRY_KEY}" "VR SPORTELLO" 1

SectionEnd


Function ${un}CLIENT

IfFileExists $INSTDIR\$PathClient\VR_CLIENT.exe 0 Fine3

!insertmacro UnInstallLib REGDLL SHARED REBOOT_PROTECTED "$SysDir\XPCONTROLS.OCX"

DeleteRegValue ${UMUI_PARAMS_REGISTRY_ROOT} "${UMUI_PARAMS_REGISTRY_KEY}" "VR CLIENT"


Fine3:
Nop

FunctionEnd

Function ${un}SPORTELLO

IfFileExists $INSTDIR\$PathSportello\VR_SPORTELLO.exe 0 Fine4

!insertmacro UnInstallLib REGDLL SHARED REBOOT_PROTECTED "$SysDir\XPCONTROLS.OCX"

DeleteRegValue ${UMUI_PARAMS_REGISTRY_ROOT} "${UMUI_PARAMS_REGISTRY_KEY}" "VR SPORTELLO"
Fine4:
Nop

FunctionEnd

If $ALREADY_INSTALLED is not empty, it won't increase the share count as your installer has probably already done it the last time it installed your application.

First of all, thanks for your replya.

Please, verify my code.

I want to install 2 different application (Section SecClient, Section SecSportello), and individually un-install. In this way each application must manage the share count.

If my code in OK for my idea, what else dosn't works?

Thansk again for a new reply
