Lỗi : "corflags : error CF001 : Could not open file for writing" when trying to modify a Controller EXE file November 5, 2014

Problem(Abstract)

Customer is trying to use ‘corflags.exe’ to modify a Controller executable (for example to solve problem in separate Technote 1508588). An error appears.

Symptom

corflags : error CF001 : Could not open file for writing

Cause

The operating system cannot modify the EXE file.

There are several possible causes for this:

Scenario #1 – Windows user running the command prompt does not have NTFS write access to the file
Scenario #2 – EXE file has the “read only” file flag ticked
Scenario #3 – Someone has got the EXE file (for example the program is running in Windows)

Resolving the problem

The solution varies depending on the cause:

Scenario #1 – Modify NTFS permission, or launch Command Prompt as a different (administrative) user
Scenario #2 – Right-click on the file, click “properties” and untick “read only” attribute.
Scenario #3 – Close the EXE file (currently running in Windows).

Nói chung là khi tạo mới hoặc copy thư mục lên Server thông qua Veeam thì bị cái lỗi mắc dịch này.
Chi tiết thì nó có ở đây trong KB : http://www.veeam.com/kb1524
Nguyên nhân lỗi: Do Veeam FastSCP không hỗ trợ hệ điều hành 64bit.
Cách giải quyết: mặc dù nó không cung cấp gói hỗ trợ cho Windows 64 bit, tuy nhiên thì có thể giải quyết như sau:

Download the Microsoft .NET Framework 2.0 SDK (64-bit version) from the Microsoft website.
Install the SDK on a 64-bit machine where you want to run Veeam FastSCP.
Open the command prompt (go to Start > Run, type “cmd” and press Enter).
IMPORTANT: You must run cmd as Administrator.
Change the directory to: C:\Program Files\Microsoft.NET\SDK\v2.0 64bit\Bin.
Run the following command:
corflags “C:\Program Files (x86)\Veeam\Veeam Backup and FastSCP\VeeamShell.exe” /32BIT+
Run Veeam FastSCP again.
