Windows 10: Cannot install a 3rd party application on Windows 10 laptop

We just purchased a qnap nas server and we have been having issues with credentials on our laptops when interfacing windows explorer's mapped network drives with our nas. On one specific laptop we are unable to even install qfinder pro and we continually get the error "cannot find file\c\users\username\downloads\..."

Unable to install any 3rd party applications

I have a nokia e61. I have been trying to install 3rd party apps like newsgator, truphone, google maps etc on my phone. It dowloads the applications and immediately thereafter gives me a message 'Unable to install'. Any suggestions anyone.

 

Installing 3rd Party applications

My device seems to be application locked. How can I change the security policy to allow me to install 3rd party/ unsigned applications? I purchased a device that shipped with skype mobile, although skype mobile will not complete the installation. I've
looked at the registry, and I can clearly see 4 registry keys that would prevent unsigned applications from installing, but I am unable to apply any changes that I attempt to make to the registry.



I've tried to install programs that would allow me to edit these settings directly from the unit but of course, they are 3rd party applications. Does Microsoft have a signed utiltity that would allow me to change the registry? I've seen that people have
put together *.cab files that will change these settings automatically but just as before, the system will not complete running the file since it is unsigned.



Please help?



Thanks,



Chris Foster
