The NSIS errors may occur under one of the following conditions:

Note: Try to install your software after each task.
1.Delete the cache of your Web browser. To do this, in the Microsoft Internet Explorer 8 window, open Tools menu and then select Delete Browsing History….Next, click the Delete All button and also select the check box in the confirmation box that is displayed. Finally, click Yes to completely clear the browser cache.
2.If the name of the downloaded installer files comprises multiple words, rename it to have only one word, say, SoftwareNameInstaller.exe.
3.If available, download the software installer file from another approved source.
4.Update your antivirus/Security software program.

I would suggest you to check the Windows Installer Service and check if it helps.
a. Click Start, in the start search box, type Services and press Enter.
b. Scroll down and find the Windows Installer. Double-click “Windows Installer” in the Services list.
c. On the General tab, make sure the service is started under “Service status”.
d. If the service is not already running, under Service status, click Start, and then click OK.
Unregister and re-register the Windows Installer
a. Click Start Orb, in the start search box, type MSIEXEC /UNREGISTER, and then click OK.
b. Click Start Orb, in the start search box, type MSIEXEC /REGSERVER, and then click OK. After you run this command, the operation is complete.
