Re: your installation of qlikview has exceeded the maximum number of document recoveries allowed
Are you using any license? The documents which you are opening is created in the same machine and by the same user? If you are not using any license and the files which are not created by the current user and created in different machine then you can open only 4 files, after that you will get this error message.
To overcome this you need to buy a license or lease Named CAL from your Qlikview server if you have.
