由於CE5出現了問題，全部卸載後再重裝後執行菜單中target下的Connectivity Options...時出現如下錯誤：
我係統中已經安裝有vs2005及CE6。百思不得其解，按照網上的解決方案
1) Shutdown all instances of PB (version 5.0 and later) and make sure
Cepb.exe, CeSvcHost.exe (CeSvcH~1.exe) and DeviceEmulator.exe are gone from
the task manager.
2) Back up the C:/Documents and Settings/<user>/local settings/application
data/microsoft/corecon folder
3) Purge that folder [This will destroy all previously configured device
settings. It is important to make a backup as in step 2 if you need to
retain the other device settings and revert back].
4) Back up C:/Documents and Settings/all users/application
data/microsoft/corecon/1.0/addons folder to something outside of
5) Purge that addons folder under the corecon/1.0
6) Create a new one by that name under the corecon/1.0 folder
7) Copy C:/Program Files/<PB Install folder>/CoreCon/SDK/XSL/Addons/*.xsl to
the new .../coreCon/1.0/Addons folder you created.
8) Also copy C:/Program Files/<PB Install
folder>/CEPB/bin/microsoft.platformbuilder500.servicecategory.xsl to the
above addons folder.
9) Relaunch PB and try creating and configuring a new device.

也不能解決，後不得已在虛擬機的乾淨的系統中重新安裝CE5後再把C:/Documents and Settings/<user>/local settings/application
data/microsoft/corecon 目錄下的所有文件複製到出錯的系統中相應的目錄覆蓋原有文件後解決，也可以從其它正常使用的系統中的相應文件拷來覆蓋
這個問題估計是微軟在卸載CE5時沒有卸乾淨的緣故。
