Visual C++ saving task error 80070005

[EDN Admin]

Hi, All,<br/>
<br/>
Last week I downloaded and installed Visual C++ 2010 Express(Free). My OS is Windows7 Professional. I also copied Microsoft "Time Trigger Example(C++)" code as following.
Unchanged any code except the start time to 1 minute after current time:<br/>
<span class="x_x_x_Apple-tab-span" style="white-spacere
<pre style="font-size:12px; padding:5px; font-family:Consolas,Courier,monospace; word-break:break-all; word-wrap:break-word; line-height:normal hr = pTimeTrigger->put_StartBoundary( _bstr_t(L<span style="color:#a31515 "2012-07-21T18:05:00") );[/code]
<br/>
After built and ran, it was successfully opened Notepad after 1 minute. Today, a prompt from Microsoft said, only 22 days left for expiration if I do not registration the Visual C++ 2010 Express (if registered, continue for free). Then I registered and got
the registration key to licence the software. But I found when I built and ran the Time Trigger Example(C++), it always got "Error saving the Task: 80070005" at last code block:
<pre style="border:none; font-family:Consolas,Courier,monospace; outline:0px; padding:5px; list-style-type:none; word-wrap:break-word; text-align:left; color:#333333; word-break:break-all; font-size:12px; line-height:normal <span style="border:0px; font-style:inherit; font-family:inherit; margin:0px; outline:0px; padding:0px; color:green // Save the task in the root folder.[/code]
The "hr" value is always "E_ACCESSDENIED"<br/>
<br/>
Anybody has clue about this issue?<br/>
<br/>
Many thanks in advance!
