Installer takes a long time to load

[Mircea M]

Hi,

I have a question which may or may not be related to NSIS 3. I have noticed that the installer that I am working on takes a long time to load. By loading time I mean the time after the user 2x Clicks the Setup.exe until something appears that the user can see, which tells him that something is happening. On an SSD disk it takes 10-15 seconds, on a "normal" disk, up to 40 seconds. It seems to be independent of UAC enabled / disabled.

During this time I can already see the Setup.exe process and it is using a small part of the processor. There appears to be no HDD activity though, at least not something substantial (so no idea why SSD is faster).

I also don't always see the "Verifying installer" and "Unpacking" messages either. When do these two messages come?

Now I wouldn't mind this that much but from a user perspective, it is unacceptable. I wanted to ask if anyone experienced something like this or if there are any tips on how to optimize the Installer scripts so that it loads faster.

Thanks,
Mircea
