I have been trying to install Notepad++ v6.5.5 on a new computer running Windows 7.
After installation by running the installer in Admin mode, if I try to start it from the Start menu, then a warning message pops up "Do you want to allow the following program from an unknown publisher to make changes to this computer?". If I click no, Notepad++ is not started. If I click yes, then Notepad starts in Admin mode (the title of the window says "... Notepad++ [Administrator]").
I have tried uninstalling, clearing the C:\Program Files\Notepad++ directory, downloading the zip package, and then unzipping into the directory. This makes no difference, When I double click C:\Program Files\Notepad++\notepad++.exe, the same warning message as #3 appears.
Does anybody know what I may be doing wrong? Running Notepad++ in Admin mode means I cannot drag and drop documents, which makes it much more difficult to use.
Go to the directory where N++ is installed, right click on notepad++.exe, select Properties, select the Compatibility tab, uncheck "Run this program as administrator". Might work.
I found "Run this program as administrator" checked and greyed out. I had to click the "Change settings for all users" button underneath before a new pop-up window allowed me to uncheck it.
After that it works a treat. Thank you very much for your quick response.
