MicroStation can use more than 4GB of physical memory on computers running Windows x64. See MicroStation Memory Management for details. Due to the enhanced security model of Windows 7 through 10 and Vista, MicroStation is prohibited from enabling the "Lock Pages In Memory" privilege unless user access control is disabled or MicroStation is run with administrator privilege.
The simplest workaround is for the user to disable user access control, but it is likely some users and/or system managers will find that unacceptable.
Another workaround is to run MicroStation with administrator privilege. To do that, the user must have administrator privilege and must request that MicroStation run with administrator privilege. A user with administrator privilege can start MicroStation with administrator privileges using one of two approaches.
When the user starts MicroStation with one of these approaches and the User Account Control: Behavior of the elevation prompt.. is not set to Elevate without prompting, Windows will go through the standard process of asking the user if it is okay to allow the program to run.To turn off the elevation prompt, change the User Account Control: Behavior of the ele... value in the Local Security Policy dialog. You can get to this dialog from Control Panel (Classic View) > Administrator Tools or by running SECPOL.MSC.
Once you are in the dialog, you can get to the item from Security Settings > Local Policies > Security Options.
There are a number of ways to enable/disable User Access Control. The simplest is to open the control panel and enter UAC in the search panel. That causes the Control Panel to display a link you can use for controlling UAC. This approach does not work when the Control Panel is in Classic View.

Ok, so I followed the instructions and I can Run MicroStation as Admin, but MicroStation only opens in the "Out of the Box" scenario. not much help,when I need to use networked workspaces.
brownlg33, if you haven't heard already - the CONNECT edition of Microstation, which is currently in its' Early Access phase, will be 64-bit. You can actually test the program out yourself now!
I now see the other article referenced talks about enabling Lock Pages. You should consolidate the two articles for one complete solution. What would be even better though is releasing 64-bit MicroStation!
I have tried this and it's not simply a matter of disabling UAC or running MicroStation as Administrator. These things alone will not allow MicroStation to use additional physical memory. At least in our environment, "Lock Pages In Memory" has to explicitly be enabled in Local Security Policy settings and *then* MicroStation has to be run as administrator.
