Windows XP Home SP1 with 256Mb RAM. Apart from the following, my computer works perfectly!!!!! 1) When I open My--------> Documents; Computer; Networks; Shared Folders; Unused Desktop Icons plus Internet Explorer and Recycle Bin from Desktop Shortcuts and Windows Explorer from the Start Menu-->Run, I get the following error messages "Bitmage image is not valid" (OK) then "BHO cannot create SMUBO" (OK). The respective Folders then open normally. 2) When in Internet Explorer I select Internet Options from the Tools menu, I get this error message: "Restrictions - This operation has been cancelled due to restrictions in effect on this computer. Please contact your System Administrator". I am the sole user and System Administrator. This option works perfectly in MYIE2 and Dominica; both are based on the IE-engine. 3) I`m trying to install the latest version of 602 PC Suite, downloaded from the Internet. When the preparing set-up screen is opened, aguage loads to approx. 95% and then the following error messageappears: "Unhandled Exception - Error No. 0x80040706 Description: Object reference is not set. Set-up will now terminate" This is the only dowload I`ve been unable to install. Any rational suggestions would be appreciated. Many thanks.
