安装PB4.2的问题

我在公司的机器上面安装PB4.2，没有问题。
可是回家在我自己的机器上面装，装完后，点击 new platform，就会出现错误提示：
Unable to locate any installed processors.
Please reinstall Platform Builder.

Missing or corrupt Platform Wizard file (ceplatwz.pbx)
Unable to continue with the Platform Wizard.
Please reinstall.
请问这是怎么回事啊，两台电脑都是winxp professional+SP1,公司是局域网，家里也是，3台电脑组成局域网，有ADSL Medom做路由器上网。
谢谢

this problem maybe due to the reason without visual studio.net supporting ,or  you may try install a  visual studio .net, or  you may have a try to register scrrun.dll, then uninstall the wince, reintsall all wince, it will be ok.

   go into C:\Program Files\Windows CE Platform Builder\4.20\cepb\bin (or
wherever you installed PB to)
    back up the file pbcpudb.mdb (rename it to something like
pbcpudb_old.mdb)
    make a copy of the file t_pbcpudb.mdb and rename the copy to pbcpudb.mdb


What this is doing is replacing the CPU database created during installation
(containing information about which CPUs you installed) with a copy of the
CPU database that would be created for a Full Installation.  So, when you go
to create a new platform in PB, you will actually see CPUs/BSPs that you
haven't actually installed, but you should be able to create platforms for
the CPUs you selected (CEPC, Geode, Emulator.)
