OK, I did that -- changed the name of the folder to C:\ProgramData\opencpn.bak.
Clicked on shortcut, and I get a message box titled "crInstall error, Crash Reporting disabled" with the message "Couldn't create crash report directory."
Clicked on OK button and got a second message box "OpenCPN Error" , "Directory 'C:\ProgramData\ opencpn\CrashReports' couldn't be created (error 3:the system cannot find the path specified.)
Clicked on the second OK button and got the "Welcome to OpenCPN.. Version 4.2.0" message box with (I think) the standard disclaimer.
Clicked on that OK button and the program started, without any
charts loaded, presumably because they are in the folder which is now OpenCPN.bak. I loaded a chart directory and everything seems to be working fine. As you probably know, but I report for completeness, there is now a new folder "C:\ProgramData\ opencpn" with four files:
CHRTLIST.DAT
navobj.xml
opencpn.ini
opencpn.log
OK, you say "If it helps, we would much like to see the contents of opencpn.bak." That's fine, but in what detail? There are eight folders and twelve files.
"C:\ProgramData\opencpn.bak\navobj.xml"
"C:\ProgramData\opencpn.bak\navobj.xml.1"
"C:\ProgramData\opencpn.bak\navobj.xml.2"
"C:\ProgramData\opencpn.bak\navobj.xml.3"
"C:\ProgramData\opencpn.bak\navobj.xml.4"
"C:\ProgramData\opencpn.bak\navobj.xml.5"
"C:\ProgramData\opencpn.bak\navobj.xml.changes "
"C:\ProgramData\opencpn.bak\opencpn.ini"
"C:\ProgramData\opencpn.bak\opencpn.log"
"C:\ProgramData\opencpn.bak\opencpn.log.log"
"C:\ProgramData\opencpn.bak\CHRTLIST.DAT"
"C:\ProgramData\opencpn.bak\MMSINAME.CSV"
"C:\ProgramData\opencpn.bak\Charts"
"C:\ProgramData\opencpn.bak\CrashReports"
"C:\ProgramData\opencpn.bak\gshhs"
"C:\ProgramData\opencpn.bak\gshhs standard"
"C:\ProgramData\opencpn.bak\layers"
"C:\ProgramData\opencpn.bak\SENC"
"C:\ProgramData\opencpn.bak\UserIcons"
The Charts, layers, and UserIcons folders appear to have nothing odd in them. "gshhs standard" is a backup -- I use the high res map. I've never noticed the CSV before -- it appears to be a list of all the name/MMSI numbers the system has seen -- I assume that allows the system to put a name on an MMSI number before it's actually "heard" over the
radio.
