I have 2801 router with the IOS 12.4(20)T1, when try to install the sslclient-win-188.8.131.52.pkg in router through SDM(2.5). I am facing problem, error message is poping up saying that error "installing package: unknow error
This may if your router uses LEFS file system converting it to Use a DOS file system may resolve the issue".
Through the wen serach i got some recommendation to do the format of flash disk and copy IOS and SDM. But it could not help.
can any one help me.
