How can we uninstall de DuckDB ODBC throughout command line.
I've tried already the odbc_install.exe /uninstall and it doesn't work.
Thanks in Adv

odbc_install.exe requires Administrator privileges. But it also support running in a non-privileged shell, in this case it request permissions elevation (UAC screen is shown) and re-launches itself with the copy of input arguments.

The routine that copies the arguments is buggy, and wrong string was passed to the re-launched utility.

For installation - no arguments required (/Install argument is optional), so it was working correctly with both Admin and non-Admin launches.

For uninstallation, it is necessary to specify /Uninstall argument (with this exact capitalization and the forward slash). So uninstallation only works from the Admin shell.

Also note, that the driver uninstallation uses UsageCount value from registry, if the installation was run multiple times (for example, running odbc_install.exe without arguments accidentally) - then it is necessary to run odbc_install.exe /Uninstall multiple times too.

I've filed #54 to fix this.
