On my Windows 7 64-bit, Notepad++ nor its PortableApps.com equivalent won't launch. The process and the splash appear, but beyond that it doesn't work, splash doesn't disappear. Its been like that since I installed NP++ on a clean Windows 7. I couldn't find any similar reports from Google either. Uninstall/install won't help. Tried multiple versions over the few months, its all the same.

Any further ideas what to try next? I fail to believe its Notepad++'s problem...

After attempting to open it, is the Notepad++.exe visible in the Processes tab of your Task Manager? – Mark Sep 2 '10 at 16:39
Yup, its nicely sitting there. – Tuminoid Sep 2 '10 at 16:47

i have win7 64 and it's running perfectly, so it's probably not a notepad++ error – inf.ig.sh Sep 2 '10 at 16:50
When the splash hangs, does the cpu utilization of NPP stay high/even rise or does it fall to 0%? Where is NPP installed? – Andreas Sep 2 '10 at 19:14

I was going to ask about the splash. Are you using the ANSI or Unicode version? What is the file hash of the EXE? On my system, they're ANSI: D809BF9D4AB81F61E28E70B66640C96B, Unicode: A2635D8A9CF8FE426ABCE48BF4C89BB9. I'm also Win7 x64. (Are you x64 or IA64?) – BillP3rd Sep 7 '10 at 3:37

Try removing any residual files that it can leave behind. I'm not familiar with the portableapps version but the normal install will store files in %appdata%\Notepad++. (You can type %appdata% in the run box to get there, if you want to go by hand it's C:\Users\username\AppData\Roaming). Delete the Notepad++ directory there and try launching it again.

Getting rid of the directory helped, it seems there was some trash from previous versions it couldn't handle. – Tuminoid Sep 16 '10 at 3:05
