Change IE start page from my program - how? Chris Shearer Cooper <chris.shearer.cooper[ at ]gmail.com> 12/15/2008 6:11:30 PM During installation, my program asks the user if they want to change their browser start page, but even if they say "Yes" I'm unable to modify the registry. If I open HKEY_CURRENT_USER\Software\Microsoft \Internet Explorer\Main with KEY_READ and KEY_WRITE permissions and then try to modify the "Start Page", it returns error 5 (ERROR_ACCESS_DENIED) and since I get an obnoxious error message when I try to modify the item directly (in regedt32), I believe my code is doing the right thing and it's some new Windows security thing. What does my program need to do, in order to convince Windows (both XP and Vista) that this operation is OK? A manifest with some magic value inside? Code-signing the app? Yes, I realize it is very likely that the anti-virus program will then pop up and warn the user that this is happening, that's expected and acceptable. Thanks in advance, Chris

Re: Change IE start page from my program - how? "Inside The Registry" <info[ at ]insidetheregistry.com> 12/28/2008 10:38:05 AM Hi Chris, I suspect your not opening the key with enough permissions such as the ability to manipulate values... Try opening the key with full rights, KEY_ALL_ACCESS if i'm not mistaken and see if that helps - it's a HKCU key so you're safe to do that... As you saw, error code 5 is access denied and given this is a HKCU key / value you really shouldn't have a problem. There is nothing I know of that puts such security methods to prevent this - Cheers, Jon The Windows Registry Information Database - http://www.insidetheregistry.com --- "Chris Shearer Cooper" <chris.shearer.cooper[ at ]gmail.com> wrote in message news:e359744b-9438-43ec-a351-9ce29faf9833[ at ]s9g2000prg.googlegroups.com...
