Removed CompareDLLVersions ?
Why is CompareDLLVersions removed in NSIS 1.6? I need it for my installers :mad: Is there other function I can use?

Thanx.

Other DLL function (from the version history):

Removed CompareDLLVersions, CompareFileTimes, added GetDLLVersion, GetFileTime, GetDLLVersionLocal, GetFileTimeLocal, and IntCmpU.

You could use GetDLLVersion and GetDLLVersionLocal instead of CompareDLLVersions

See UpgradeDLL in functions.htm for an example.

Thanks.

So i should use something like: If GetDLLLocalVersion(DLLName) > GetDLLVersion(DLLName) then CopyNewDLL ?

I'm new to the NSIS system, so i'll have to find out how I can do this is the NSIS language :D

I think you could use it in this way:


ClearErrors
GetDLLVersionLocal "test.dll" $0 $1
GetDLLVersion "$SYSDIR\test.dll" $2 $3
IfErrors upgrade_dll
IntCmpU $0 $2 noupgradedll noupgrade_dll upgrade_dll
IntCmpU $1 $3 noupgrade_dll noupgrade_dll
upgrade_dll:
    UnRegDLL "$SYSDIR\test.dll"
    File /oname="$SYSDIR\test.dll" "test.dll"
    RegDLL "$SYSDIR\test.dll"
noupgrade_dll:

I just wrote some code similar to your code, with some reboot stuff included. But, I only compare $0 and $2, and it seems to work. Should I also compare $1 and $3 ?

Strange, I've done some testing and now I'm using your code, but it always detects that the integers are equal, but they are not :(

Problem solved ;)

I'll have to compare only the large integers, because only the build numbers are different.

IntCmpU $1 $3 noupgradedll noupgrade_dll upgrade_dll

Now the next problem :D

How can I register a DLL on reboot ??

Hi Joost,

I don't know how to register a DLL on reboot, but you could use the RegDLL command to register your DLL immediately.

That's true. When the DLL is not in use, I register it with RegDLL, but when the DLL is in use, it should be done after the new DLL is install (on reboot).

Only an idea ;):

Try to write an entry at HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\RunOnce to make a call to regsvr32.exe yourdll.dll.

Good idea :D

I have to find out how to make this 'silent'. And, is this being called AFTER the NSIS 'Rename on reboot'?

I'll check where NSIS puts the 'Rename on reboot' stuff :)

In Win2000: It it stored in a PendingRenameOperations key.

Maybe I should write a piece of code that checks which one is called first.
