Hi - completely new to Windows 10 and I inted to stay that way. I m configuring a brand new HP laptop running Win10 Family for someone who also wants Skype, Fx and Tb 38.5, Avast and Libreoffice. The laptop has some 800GB of free disk space in C:\. I installed and configured all of the above without an itch except for Tb. I now have an issue with the Tb install that I can't wrap my brain around. Help would be welcome.

I downloaded the Tb setup executable from the Mozilla page (in all 33,346 kB) into the default Win10 download folder. Double clicking on it takes me through the usual succession of setup windows, then suddenly always when the actual install is to start I get the message: "You do not have write permission on the folder you chose for installation. Click on ok to selct a different folder."

The folder in question is: C:\Program Files (x86)\Mozilla\Thunderbird\ for the administrative user. Prior to installing Tb, I had installed Firefox successfully on C:\Program Files (x86)\Mozilla\Firefox\ I am really stumped. I tried the install with another user on the same machine, at the same location (user wise), with and without admin provileges. to no avail. It looks like Win10 won't let it install in C:\Program Files (x86)\Mozilla\Thunderbird\

On the other hand I can install it wiythout any problem at C:\Program Files (x86)\Mozilla Thunderbird\ (Note I took the penultimate \ out in that last path). What gives ? Does somebody have an exlanation for this ? Cheers, -ced.

@Matt, I did try deleting even the Mozilla folder and starting by installing Tb first under : C:\Program Files (x86)\Mozilla\Thunderbird\ then re-installing Firefox under : C:\Program Files (x86)\Mozilla\Firefox\ to no avail. It just seems that Thunderbird does not want to install just there. The message is puzzling too. No install privilege for that folder ? Really ? Th only thing that comes to my mind at this point that it is just that Mozilla's make file for the install of Tb, does not let it be installed in a folder called Mozilla. It will let Firefox be installed in such a folder though. So in the end, what I did was to install both programs side by side as:

1) C:\Program Files (x86)\Mozilla\Mozilla Thunderbird\ 2) C:\Program Files (x86)\Mozilla\Mozilla Firefox\

That seems to have caused no bell to ring and I am fine with that.

@Wayne: I always install everything as admin, either because I installed from the admin user account and make the app available to all users on PC or because I installed with "right-click/install as admin" from a non-admin user account. In this case I tried both. In both cases installing Tb UNDER the Mozilla folder resulted impossible.

This will go down as one of those things impossible to understand unless someone from Mozilla gives me the code for the install "make file", so I can have a peek in it.

Thanks much in any case for your help guys... smack in the middle of revelries.... and stop eating so much turkey (if turkey is what you have at and around Christmas time !).

CASE CLOSED.

Is this the 38.5 installer?

more options

Yes, it is. And there is no way I can install this under .../Mozilla/Thunderbird/ . I checked that I could install Tb pretty much anywhere else on my HD but not at that location. o_0 Seltsam, oder ?

Does that location exist? if so can you delete it and try again?

Right-click on the install executable and select "Run as Administrator". Results?
