I am thinking this is an access rights issue. Getting weird messages like:

"Install may need an extra [1263372293]KB on drive W. If the drive has over 2TB free [which exceeds the ability of the install to detect] the above message can be ignored and you can press the Ignore button to proceed.

Otherwise free up enough space and then Retry."

Well there is clearly disk space galore. So I Ignored and ploughed ahead then received another Error:

"The file W:\Softrak\system\CR_InstallCommon\webfiles.ini could not be opened. Please check that your disk is not full and that you have access to the destination directory."

So clicked on "OK" from above message and now it hangs on the following Error:

"The file W:\Softrak\SYSTEM\SS12MDB.DLL could not be opened. Please check that your disk is not full and that you have access to the destination directory."

To reconfirm, internet is up and running since I did a fresh download of the Ledger download and AV has been disabled.

Thanks for any information.
