NSIS issue when installing application

Would have to see your NSIS script to help, but even without seeing it, here's one thought — maybe you're using an old version. I recently updated to version 3, beta 3 and it is performing very well — fixed numerous problems that I had in earlier versions. Although it's still considered a beta, it has been rock solid for me, with zero problems (even !finalize is working well to sign the installer with a code-signing certificate). Download is here:
http://nsis.sourceforge.net/Download

That link also has the latest production release (2.50), but I highly recommend the beta (3.0b3). Regards, Joe

Thank you for your fast reply. I tried it, but it could not work

Did you get the same error dialog box? If not, post the error you received. In any case, I can't help further unless I see the script.

All are the same as before

OK, then there's nothing I can do to help you without seeing the script, as "NSIS Error > Error launching installer" is too generic to figure out what the problem is based soley on that error message. Regards, Joe

Clicking that link leads to the page which can download two files, one is NSIS 2.50, another is 3.0b3. Installing 3.0b3 can not make the application work, then when I installed 2.50, I got the same error message as that attached picture in my first post. That is all message that I have so far.

I think I was misunderstanding your problem. At first, I thought you were having problems with an installer that you built with NSIS — that's why I kept asking you for the NSIS script. Now I think what you're saying is that the problem is installing NSIS itself. To be clear, are you saying that you tried to install both 2.50 and 3.0b3, and that neither one would install?

No, I just want to install an application--Jins. When I am doing so, I get the error message which I attached in my first post. Then you said i need to install NSIS. so I did it based on what you said. After I installed 3.0b3, the application--Jins still cannot be installed due to that error message that I posted. Then I tried the second version 2.50. When I did so, I got the same error message as I installed the application--Jins.

OK, I completely misunderstood your question. I never heard of Jins, but apparently it is an app whose installer was built with NSIS. The user does not have to install NSIS in order to run an installer built with NSIS. The reason I told you to install NSIS is because I thought you were building an installer with it. You may, of course, uninstall NSIS (via Control Panel>Programs and Features).

The problem is with Jins. There's a bug in its installer. Or maybe the installer (setup) file is corrupted. First thing I would do is re-download the Jins installer. If it still fails, the next action is to contact Jins. Regards, Joe

I will try it

OK, looking forward to an update.

cannot work

Thank you. it works

You're welcome. Please let me know what you did to make it work this time.

the software itself issue. you are right
