The answer for searching a post from the Internet is roughly the same: the user logging on to the website has no operationExcel. EXE permission
Run "input dcomcnfg.exe to start" component service ". You can also enter it from the management tool,
"Component Service"-> "computer"-> "my computer"-> "DCOM configuration"-> find the word-> properties-> "ID" tag, select "Interactive User"
-> Security "tag"-> click "Custom" on "Start and activate Permissions", and then click the corresponding "edit" button, in the pop-up "security" dialog box, add a "Network Service" user (note that you must select the computer name) and grant it the "local start" and "Local activation" permissions.
-> "Security" label, click "Custom" on "Access Permissions", and then click "edit ", in the pop-up "security" dialog box, add a "Network Service" user and grant "local access" permission. in this way, we have configured the corresponding Excel DCOM permissions.
Note: The 64-bit system cannot find the reason for the office component service:
The main problem is the 64-bit system. Excel is a 32-bit component, so it cannot be seen in normal system component services.
You can enter comexp. MSC-32 in the run to open the 32-bit component service, and then you can see the Excel component in it.
