Error deploying SharePoint 2010 solution with InfoPath form (The path is not of a legal form.)

Question

I am new to SharePoint and .Net development, sorry if answer for my question is obvious.

I've created SharePoint solution, which uses InfoPath form. When I deploy it from Visual Studio, all work fine, but when I try to deploy WSP package from web interface it fails with error:

[ArgumentException: The path is not of a legal form.]

My module Elements.xml:

<?xml version="1.0" encoding="utf-8"?>
<Elements xmlns="http://schemas.microsoft.com/sharepoint/">
  <Module Name="Forms">
    <File Path="Forms\CustomTaskForm1.xsn" Url="Forms/CustomTaskForm1.xsn" />
    <File Path="Forms\CustomTaskForm0.xsn" Url="Forms/CustomTaskForm0.xsn" />
    <File Path="Forms\CustomTaskForm7.xsn" Url="Forms/CustomTaskForm7.xsn" />
    <File Path="Forms\ApproveTaskForm.xsn" Url="Forms/ApproveTaskForm.xsn" />
  </Module>
</Elements>

There is an answer to the problem here, which tells that the error occurs then Path attrubute is incorrect, but I can't understand what directory is current and how I have to change the Path attribute. Could you help me, please?

Thank you in advance.

UPDATE1: Thanks to Kai answer, solution was found. There was an error in my Feature.Template.xml:

<?xml version="1.0" encoding="utf-8" ?>
<Feature xmlns="http://schemas.microsoft.com/sharepoint/">
 <ReceiverAssembly="Microsoft.Office.Workflow.Feature, Version=14.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c"   ReceiverClass="Microsoft.Office.Workflow.Feature.WorkflowFeatureReceiver">
 <Properties>
   <Property Key="GloballyAvailable" Value="true" />
   <Property Key="RegisterForms" Value="Forms\*.xsn"/>
 </Properties>
</Feature>

When I removed ReceiverAssembly element, all deploys succesfully.

UPDATE 2: But now I have got next question. When I deploy my solution, it deploys without errors, creates all lists , but I can't see my workflows. When I deploy it using VS2010 all works fine (workfows shown and associated with lists).

UPDATE 3: Actually, it doesn't work... when I remove ReceiverAssembly element it only deploys without error, but when I choose task (and InfoPath form have to start), it fails... When I change my ReceiverAssembly element how Kai shows, it deploys from VS, but not from WSP again...

UPDATE 4: Hurray! Now it works! Thanks to all!

Answer 1

As per msdn - DirectoryInfo -

ArgumentException - path contains invalid characters such as ", <,> >, or |

Path in your situation is featureDef.RootDirectory (by stack trace I can see that you are using WorkflowFeatureReceiver, so check out method EnumerateFormTemplates using Reflector). Check if path to your feature contain not legal characters.

Answer 2

I've found the answer. Now it works. It seems like the root of the problem is next: I've tryed to add WSP Farm solution to sandbox solution gallery. I have to use another way for deploying, for example PowerShell.
